Amazing how many movies I came into mention have already been mentioned. My first thought was
**Superbad **- An amazing piece of shit. I did not get the appeal or popularity, but was told it was incredibly funny and a must-see.
E.T. - I couldn’t stand Drew Barrymore then, and I still can’t stand her. And the movie sucked (to me) too! I remember being the only person that didn’t like it when it came out.
Sexy Beast - Wow. A complete puzzlement to me. The only thing I remember about the movie is the “fuck fuck fuck fuck fuck fuck fuck fuck” line by Ben Kingsley.
Forrest Gump - I thought I was going to lose my mind watching this thing. And it won Oscars! Best Picture? Tom Hanks as Best Actor? I ***still ***don’t get it. To me, this is like the Bizzaro World picture.
**Titanic **- Jack! Rose! Jack! Rose! - I laughed out loud when the poor bastard fell from the back of the ship and hit the propeller, drawing angry looks from all around (including my date). That was the best part of the movie.
I will defend a couple of movies that have been mentioned, to show that I don’t think I have perfect taste.
Napoleon Dynamite - Really liked this movie, and I wasn’t expecting to. But it made me laugh. The best scene was when the farmer shot the cow with the school bus full of children driving by (and you hear them screaming). Not the greatest movie ever made, but I did enjoy it.
Saving Private Ryan - The movie for me is really the battle scenes, particularly the Normandy landing. Watching that really gave me an appreciation for WWII veterans who had to go through that particular horror, seeing the landing craft door drop and watch those guys get shot from the pillboxes on the beach. How they were able to drive themselves forward is a fascinating study in human perseverance.
Finally, a comment on some older movies that have been mentioned. The Hitchcock movies have always been highly touted as great, suspenseful cinema. And they probably were when they were released. However, they just don’t hold up today. For example
Psycho - I agree with the comment upthread about this movie. Watching it now, with present-day violence standards, is not scary at all. Maybe when it was released it was ground-breaking, but now? Marcia getting hit in the nose with a football is as violent as the shower scene in Psycho.
Strangers on a Train - A snooze-fest with a great premise. I didn’t find it scary or suspenseful at all. But perhaps when it was released, seeing a close up of a strangulation was a cutting edge, but it’s very tame by today’s standards.
