What was the worst bastardization of a classic book into a movie?

"I Am Legend" has been made into 3 or more movies, none of which have anything like the book's ending.

The Last Man on Earth (1964) is dull and misses the point almost entirely, but almost manages the title line. Not quite.

The Omega Man (1971) is exciting and misses the point even further.

I Am Legend (2007) almost gets it. The vampires are competent. Will Smith's smarter than Neville of the book, but crazier. But then both endings fail to treat the vampires as a society.

Because no one is going with the classic, I can mention Eragon.

Not a classic book, but Artemis Fowl. Disney managed to confuse fans of the books and newcomers to the series alike by adding a McGuffin that was unnecessary, bringing the antagonist from the second book into the movie on the first book, and mangling the relations between the two main protagonists beyond recognition.

The Wheel of Time. I waited for reviews before watching it, so glad I never wasted a second of my life watching that piece of blasphemous garbage. Just stick to the source material, how fucking hard is it??? Apparently too hard for modern directors, they have to "fix" everything and make it appealing for a "modern audience." Bitch, I am the modern audience, and fuck you.

World War Z. Not a classic book, but still...Wtf.

I, robot.

Easily "World War Z." What an utter waste of the source material.

Possibly controversial, but I thought the movie version of Hitchhiker's Guide to the Galaxy was a huge disappointment.

Luckily there's the radio series, books, TV show, comic, play, and game to get me through :-)

The many adaptations of the Iliad, none of them is gay enough.

Starship troopers. I say this not because the movie is bad (it's not, I think it's exactly what it meant to be and did it well), but that the movie and the book are thematically opposites. The book is very pro military authoritarian. The movie is a satire of that.

No one appears to have yet mentioned Forrest Gump. In the book he was a chess grandmaster who wrestled professionally and was an astronaut. Also, the book sucks.

"Do Androids Dream of Eletric Sheep"

You'll probably recognize it as Blade Runner but the film took so much liberty the author allowed a good friend to write three sequels in order to harmonize the book with the movie.

Also "Starship Troopers".

I would say Rings of Power, then again it has basically nothing to do with any books and seems to be based on bad fan fiction.

Not a classics, but:

• American Gods: they made unnecessary changes and introduced unnecessary filler plotlines until it felt like a drag to watch. The book already explored social issues, but the showrunners decided to dial it up to 100 and spoonfeed it to the audience at the expense of the actual plot.
• Ready Player One: they dumbed down the whole thing about hunting keys and portals, removed tons of important worldbuilding details, made pointless changes that ruined the spirit of the books. They should have made it into a series instead of a movie.

The foundation series by apple is pretty bad.

How bad? The absolute best part is a part not present at all in the books (the Cleons). Everything related to the book is bastardised, imo.

Not a classic for most people but zoomers will agree that Percy Jackson and the lightning thief was a tragedy.

Oh, another one I just thought of - How to Train Your Dragon.

The movies are fine, but they are so completely different from the books in almost every respect that it's barely worth giving them the same name.

The books are absolutely brilliant, especially the further you get into them. Would love to see them developed as a TV series that stuck to the style and messages of the books. Would likely need about 10 seasons though!

The Dark Tower. I don't get what that was, the books were far richer.

Dune. The Wheel of Time series on Prime.

The Gunslinger. It was supposed to be more of a continuation of the books but it just sucked all around.

Any visual media that you've seen after you've read the source book. A better way to look at it. It is which movie was better or as good than its book.

Jurassic Park was a better movie than the book. The Martian the movie was as good as the book.

I'm going to flip the spirit of the question and say that Michael Crichton's Timeline movie adaptation is so bad that it falls into so bad it's good territory. I own it on bluray, and we watch it at least once a year.

Eragon. They really fucked up so much about the book!

Well. It's clearly not a book, but Disney's Hercules was the first time I really felt disappointed about going to the cinema. My ten year old brain was having none of it. I wanted the adultery, the murder, the dirty stuff the story was supposed to have and I think it's the Disney film (that I've watched) I hate the most up to date.

I have to imagine that Lawnmower Man is in the running. Talk about having nothing at all to do with the 'book' , (well, short story anyway).

"The NeverEnding Story" should never have been made into a movie. It's almost ironic. Every time a child watches the movie instead of reading the book, that's an opportunity lost.

Hunger games.

The Black Cauldron

Inkheart by Cornelia Funke is one of my most beloved series

read that series several times and when they announced a movie I was so hyped!

and the movie was just ok :C
I haven't seen any movies based on books since then unless it receives high praises which I haven't seen much

The NeverEnding Story

I know its not a classic, but Dan Brown's inferno the book and the movie have two different endings and it angers me every time.

Don't know if it counts as "classic", but Mortal Engines comes to mind. The film cut out over half the book. I loved the book and got really excited for the film, but it was a massive let-down. They could've easily made the film twice as long, maybe more.

Vampire$ -> John Carpenter's Vampires

I hate to admit it but it's actually worse an adaptation than the Starship Troopers "adaptation." Although admittedly I do like the JCV movie. I used to like Starship Troopers until I found out the director made a mockery of Heinlein on purpose because Verhooven is a jackass. Did you even read the book?

Anyway.

As I understand it there actually is a reason for this. Basically, a studio ends up with the rights to an IP, and they sit on it because they suck at the one thing they're supposed to be good at. Then along comes somebody with a project idea, and the studio goes, oh that's similar to something we already have in the pipe. Then they steal that idea, tweak the script to include at least one or two elements from the IP, claimants an original work and they don't have to pay the original screenwriter, and churn out something that may or may not be any good, but is nothing like the IP, thus potentially making significant profits for the executives at the meager cost of pissing off the original IPs core fan base.

The vampiers assistent, bases on the Darren Shan series. The tried to fit the first 3 books and the last one in one movie, and skipping over the other 8 books.... And who is Rebecca the monkey girl.... I wand Debbie and Sam....

Cloudy with a Chance of Meatballs should have never been made into a movie.

LXG 😬

The Lovely Bones. Haven't actually read the book, but that movie was a painful experience to get through. Peter Jackson knows how to do special effects and spends over two excruciating hours showing off all of them, even though they add little to the story which could have been told in less than half the time.

Swallows and Amazons. So disappointed.

The Cat in the Hat.

The Lost World. The movie is nothing like the book.

2009's Confessions of a Shopaholic.

The movie was decent but coming from the book, I was so disappointed in the adaption and how they basically took the entire series into 90 minutes.

Though Hugh Dancy as Luke was chefs kiss
