I'll add Crossroads and wait on Swept Away. The One fits into the Kung Fu/Karate/Martial Arts genre and most are bad and that is why they are good. Even a modern martial arts movie fits and will always have a few redeeming scenes.
I saw 8mm and thought it shouldn't be there until I really thought about what was memorable or really good about it. Nick Cage is great, but the plot and movie depended on the taboo to reel people in and ultimately it just kept getting worse and worse and wasn't really unpredictable. Mel Gibson was in a film at the same time about a rogue who wants revenge and that was good in comparrison because it was gritty, harsh and unpredictable. Mind you this is my opinion. But I thought about how I could justify 8mm as being good and ultimately I said to myself, I guess it did suck...
