Ditto, also Apocalypse Now changed my outlook on war forever.
I love Grave of Fireflies, but its that kind of movie, you just dont want to see again.
Movies like Limitless or Fight Club are pretty inspirational, if you are underarchiever in your twenties, but dont have much to offer, if you are outside of this group.
Brazil is pretty much
the only worthy movie adaptation of Orwells 1984 (despite claiming not to be one). Great, great movie.
Untypically, I really liked HK "City hero" movie about training and exploit of HK swat team. Made me really appreciate the hard work these young men do, to protect society.
