Mine has to be Alien (1979) i think it sets up the tone really well and builds up tension for the end and compared to current horror movies today it holds up.

i only really watch anime movies so possibly one of the gup movies (that involve the continuation school as they are finnish :3)

Either Hunt for the Wilderpeople or The Iron Giant.

the truman show and forrest gump

1408 is a good one.

I love that one speedrunning movie starring Brad Pitt and Robert De Niro.

I have some of them in my favorite list. But This one "The Life of PI" has taught me a lot of things. This one has shown how to survive someone in a danger situation.

Definitely RoboCop1987 and Terminator 2

Love this one Terminator 2.

Spirited Away. :)

Back to the Future or Indiana Jones and the Raiders of the Lost Ark
