Just saying here, but without some sort of clue as to what the OP or contributers think constitutes crapness in film, this isn’t the most useful of threads. Simply saying “It’s crap because it sucks”, or “I’ve always hated this film”, or “total snoozefest”, provides no information other than some vague statement about one’s personal preferences. Several posters seem to be calling consensus great films crap simply because they’ve been overexposed on television, or because one has no knowledge of the technical limitations or social mores inherent to the time when they were made.
I went over the IMDB list and of the films I’ve seen (maybe 60% of the total), I can’t say that there were any that I could call utter rubbish (no, not even the de Palma Scarface), in the sense that they were somehow more incompetently filmed, directed or acted than the general average. There were certainly some that I don’t personally care for and feel should not be on the list, that had pretentious or banal themes or cliche’d stories, but that doesn’t, on its own, make them truly crap. I will make some allowances if the film in question at least beats one over the head with some sort of extremely banal moral lesson; in that case a number of films (some mentioned below) qualify. If one simply does not get what the film is after, or completely rejects the technical or stylistic breakthroughs achieved by a given film, which clearly happens a lot with 2001, A Space Odyssey, well, that’s not my problem.
I’d tend to agree with Wendell Wagner that recent films really don’t count and I’d go so far as to say that films less than ten years old should not be on the list. Of the older films listed, the only one I personally can’t stand is Gone With the Wind, and that is really more due to a personal aversion to banal melodrama than anything else. The film itself is very well made, however. For It’s a Wonderful Life, firstly, I think a lot of people simply have somehow missed the emotional harshness and darkness of much of the film, and James Stewart’s brilliant performance therein. I also think one has to consider the times in which it was made, the general expectations audiences had of a “Capra film”, and the tyranny of the Hollywood happy ending, which in this case (for me at least) does little to mitigate the despair evident in most of the film. Oh, well, if you still hate it, no problem; after all, it apparently was less than well received at the time of release.
Of more recent films, I have no particular appreciation for David Fincher’s movies in general, American Beauty for its heavy-handedness, American History X mainly because the director has apparently disavowed the release version, Forrest Gump because I find its theme repellent, Unforgiven because there’s nothing particularly original in it, Gladiator for the same reason, and just in case anyone thinks I’m one of those Kubrick-fellators, The Shining for being all style and no substance. All of these films, however, are more or less competently made and most of them have some redeeming merits, regardless of my personal opinion of them.
