To all the movie buffs: according to u which is the most underrated movie of all time?

I dunno about under rated, but the ones I recall watching to oblivion many times over - jaws, the crow, forest gump, fear and loathing in las vegas, fantasia, fight club, buckaroo banzai, pink floyd - the wall, remo williams - the adventure begins, the jerk, pretty much all the pink pather movies from before 2000.
