What TV show were you highly excited for, but ended up quickly disappointing you?

Second season of Altered Carbon. I don't even want to explain.

The wheel of time. I'm a huge fan of the books and wanted the show to be good so badly. They took a lot of liberties with the casting ethnicity wise, which was controversial (not for me, but you can imagine the type of people that things like that matter to.) From the start I said as long as the writing, acting, set/costumes were good I didn't really care who played what. But none of those things ended up being good at all. The sets and costumes looked like something purchased at Spirit Halloween. The acting was mediocre at best, I don't mean that as a jab at the actors, even great actors need good directors and writers. Which brings me to the writing. They threw out large parts of the story to make room for new plot lines, and the stuff they added was just God awful. In the end the show got cancelled, so we didn't even get to see any of the cool late book stuff.

/End of rant

"Spirit Halloween", died. 🤣
Josha Stradowski should get a razzi for the worst acting ever performed on screen. Wooden. The problem I had overall was that it seemed like the writers were really drawing out the material. I was so bored at times, and I am a HUGE fantasy genre fan. The fact it didn't get a proper ending (mostly because it took so long to progress) was another knifing. It deserved to die, sadly.
I’ll never forgive them for not making it to Dumai’s Wells at least.
Sometimes I wonder about the timeline where HBO and those game of thrones assholes did wheel of time instead…

Second season of The Last of Us. Never played the second game so I went in blind after really liking the first season. The writing and dialogue were godawful and I just could not give less of a shit about the direction it was headed. I get that the show is more about interpersonal relations in the face of extreme hardship than killing zombies and cool action scenes, but the second season was just so slow in advancing the plot that it left me completely disengaged.

I LOVED season one, absolutely loved it. Accidentally found out the massive spoiler for part 2, didn't like it, read more about the game and made a heart rending decision to not watch s2. The plot just doesn't interest me, Joel and Ellie were the heart of it and the plot isn't credible to me. Looking at reviews, I'm glad I missed it
- Oh yeah absolutely. Without Joel, the series suffers so much because of how well Pedro Pascal nailed the role imo. It really, really wanted you to care about Ellie's relationship but I just couldn't because her character was so wildly unlikable. I didn't feel that the way the second game/season was written advanced the overarching theme of the series.
  For that reason, I'm probably going to end up skipping the upcoming season. You'd be better off exploring similar themes in different media lol

Foundation. I am a big fan of Asimov's books and the series is rare, slow and in my opinion does not understand the material of origin or the themes it deals with

I don't understand why they would take a story and then adapt it into a TV series that says the exact opposite.
I see this happen a lot with TV shows where the people who are making the show genuinely don't seem to give a shit about what was in the original work.
I get the impression that people who buy intellectual property rights to existing works actually hate those works and their fans and would like to remove the themes, motifs, and messages of the original work from the common culture altogether.
- Because the books as is are practically unfilmable.
  It’s just men around a table smoking cigars and drinking whiskey congratulating themselves how excellently their plans went.
  Time skip. GOTO 10. Riveting stuff.
  Asimov and his peers were 100% world building 0% characters and character development.

Sword of truth. It deviated from critical book storyline within minutes of the first episode

The second season of True Detective. Didn't even make it to the third episode.

The Watch.

Swamp Thing was pretty far from what I had hoped for and I think they can do more with those stories

Andor.

2nd season of Harry’s Law absolutely butchered any interest we had following season one. I think we only made it 2 episodes in before completely giving up?

i think it was a complete change of character for S1’s antagonist to join the team in S2 - but I could be misremembering…

Murderbot - The main character is nothing like the book and the Preservation team are made out to be idiots. It's really disappointing.

Sword of Shannara
