Opinions are FUN!
Spirited Away? I'd think Grave of the Fireflies or Nausicaa of the Valley of the Wind would be better choices for best Miyazaki Film.
Vertigo screwed up in the storytelling department by revealing the truth of the girl he'd been chasing too early, and the answer was implausible, then it had a ridiculous, frankly laughable ending. Harvey's a better J Stewart movie and I'd take ANY Hitchcock movie over Vertigo. Even THE BIRDS.
Citizen Kane is not the best movie ever for several reasons. It's boring, for one. Its message and riffs are not very relevant to modern times. And, by 1941, all of the supposed 'firsts' it achieved were already being done in foreign cinema.
A lot of people in here have it right. 2001: A Space Oddyssey, A Clockwork Orange, Dr. Strangelove, Psycho, there are so many better choices.
Star Wars V, Alien, T2, The Matrix, Jurassic Park, The Crow, The Dark Knight, even Avatar gave us great reasons to go to the theaters, (even if the storyline had issues, it won't matter much for people who put visuals and music ie: the 'experience' ahead of the story).
Then there's all those respectable war movies like Saving Private Ryan and Apocalypse Now. The amazing storytelling from Pixar ... 'til recently.
My favorite movie? The Last of the Mohicans. Subjective!
