No particular order, these are some of my favorites.
Alien and Aliens could be there too.
And a bunch of animates movies like Ghost in the Shell, Akira, A silent voice, Grave for the Fireflies, The Tale of Princes Kaguya, Princess Mononoke, Howls moving Castle.
Also Toy Story 2, Shrek 2, The Prince of Egypt, Fantasia, Klaus, Into the Spiderverse.
Dead Man: A film by Jim Jarmusch starring Johnny Depp and Gary Farmer and an all-star cast. Beautiful acid western about friendship in harsh circumstances. Wonderful original soundtrack by Neil Young.
The Fall: A film by Tarsem. This films story isn't necessarily amazing, but this is a love letter to classic cinema. It has a plot about classic cinema, and it uses all classic techniques to achieve the effects. Tarsem famously went out of their way to ensure there wasn't any CGI in this film. It's one of the most vividly colorful and visually stunning films I have ever seen.
Dreams: A film by Akira Kurosawa. A montage of short films inspired by dreams experienced by filmmaker Akira Kurosawa. In partnership with Lucasfilm. Almost as visually stunning as The Fall but much more cohesive stories for being inspired by dreams. Come for "The Peach Orchard," and stay for "Village of the Watermills."
Brazil: A film by Terry Gilliam starring Jonathan Pryce, Robert DeNiro, Kim Greist and Michael Palin. A treatise on dreams in a totalitarian society. The only cut worth watching is the Directors Cut. The film was famously butchered by the studios to give it a "happy ending" because the original was considered too bleak.
Sneakers: A film by Phil Alden Robinson starring Robert Redford, Sidney Poitier, River Phoenix, and Ben Kingsley. One of the only films that ever presented a semi-realistic portrayal of hacking. Good plot, good pacing, and arguably prescient considerations.
It's a toss-up on a couple of those. The Blues Brothers could easily make the list, as could Pulp Fiction, Terminator 2, Alien, Interstellar, and I'm sure there are many others. I will abandon what I'm doing to watch any one of these, if they come on, probably 90% of the time.
Runners up: Empire Strikes Back, The Matrix, Pulp Fiction, ET, Close Encounters, Alien(s), Ghostbusters, Stand By Me, Full Metal Jacket, A Bronx Tale, Good Will Hunting
I actually sat down a coworker years ago and did this. It was surprisingly easy once I realized something - I'll sit down and watch a lot of movies on TV, but there are a few I refuse to. Too many commercials and edits just make me furious... those are my favorites. Getting down to 10 was hard enough, so top 5 are in no order. Some changed how I thought about things, some just entertained me for years:
The Matrix
Interstellar
Monty Python and the Holy Grail
Fight Club
Schindler's List
And because it was so hard, here are a few more that just as easily could be top 5:
Silence of the Lambs, Inception, V for Vendetta, OG Star Wars trilogy, Indiana Jones trilogy, Kung Pow, Blair Witch Project
Edit: Forgot one - Arrival. Probably in top 5, no idea which to demote. Fight Club maybe
Super hard to limit to just 5 but here's the first that came to mind:
Star Wars: A New Hope, The Matrix, Delicatessen, The Science of Sleep, The Fifth Element.
Any of the following could easily go somewhere on the above list :)
Blade Runner, 12 Monkeys, 2001: A Space Odyssey, Brazil, The Hudsucker Proxy, Groundhog Day, Dark City, Inception & Intersteller (if only it didn't have the whole love is a force that transcends dimensions and can be used to communicate across time and space stuff?!)
Top rated because of the story (all), acting (all), music (except for 2), number of awesome quotes (3 and 4) and all in all just being amazing.
Also, since I saw someone mention it, I'd like to add that the worst movie of all time is imho 2001 A Space Odyssey. On IMDb I don't rate movies lower than 2 stars because I have 1 exclusively reserved for 2001 ASO. Watching it has been the most boring experience of my life, which btw is saying a LOT. Punishment in hell probably shifted to eternally watching this movie, with sinners wishing to go back to when they were physically tortured. I cannot stress enough how much I dislike this movie. You can be absolute sure that my top 5 is nothing like that.
Leto's performance is genuinely captivating and the storytelling is top-tier. The film strikes a perfect balance between deep emotional resonance and stunning visuals. It's not just a superhero movie, it's a profound exploration of the human condition. Highly recommend it to anyone looking for more than just escapism.
LOTR (it may be 3, but let's just call it a single movie)
Star Wars: Empire Strikes Back

Honourable mentions: anything Monty Python, Toy Story, Finding Nemo, Alladin, Indiana Jones (up to and including Last Crusade), any Bond film with Sean Connery, Die Hard, Rocky, Rambo: First Blood, The Passion of Christ, Cross and the Switchblade, The Godfather, Blade Runner, Jurassic Park

Bring It On, Liar Liar, The Hot Chick, House Party 4, and Burn After Reading
With exquisite taste, I embrace a diverse spectrum of films, from the captivating cheerleading rivalry and wit of "Bring It On" to Jim Carrey's comedic brilliance in "Liar Liar," and the hilarious escapades of body-swapping in "The Hot Chick." "House Party 4" evokes a nostalgic charm, while the Coen brothers' "Burn After Reading" showcases their unparalleled storytelling, leaving me captivated. This selection embodies my discerning taste and appreciation for a wide range of cinematic experiences.
