Some omissions are too painful to talk about: Groundhog Day, The Servant, The Lives of Others, Psycho, The English Patient. Groundhog Day is great, Psycho was an average film at best, and keeping the English Patient off your list gives you instant credibility in my mind. Still, the exclusion of Citizen Kane from a top 100 is inexcusable. I agree with vic that a waiting period to put the film in proper perspective is generally a good idea. there have been "best picture" winners that i dont think belong anywhere near the list (i'm looking at you forrest gump) while not one but two of the movies they "beat" for the award are generally considered list worthy by any sane person (shawshank redemption and pulp fiction)
