NOT your favorite, the best one you have seen. Best storytelling, cinematography, soundtrack, acting, etc. Mine: "The Shawshank Redemption", "Schindler's List", and "Forrest Gump"... I know I'm missing some, these are just a few.

I'd say Terminator II: Judgement Day. The performances, effects, cinematography, sequencing... where revolutionary for its time. James Cameron really pushed it, alog with The Abyss.
Other choices might be:
Star Wars: The Empire Strikes Back (absolute favorite Star Wars).
The Dark Knight
Agree on Schindler's List. Lets throw in Jaws, the first two Indiana Jones (Temple of Doom is underrated af), and Jurassic Park just because Spelielberg's earlier work was awesome.
Big Fish (beautiful film).
Alien (THE sci-fi horror film).
