Good: Dead Ringers - Agreed on the best performance I've ever seen from Jeremy Irons, in a dark and unique story of two twin brothers going down a self-destructive path. The twin element could have turned out to be gimmicky or corny, but it's handled perfectly.
Bad: A History of Violence - Along with The Fly, this is also one that I return to often. Accessible and rewatchable, but there are several silly elements. Ed Harris and Wiliam Hurt are both gloriously hammy villains, but they feel like they were ripped out of a more fun mainstream movie, rather than the serious tone that the storyline takes on. And when you're in the mafia, do they train you in martial arts? Because Viggo had some pretty impressive arm-locks that he displayed. Actually that was one of the giveaways for me because I've studied martial arts. If he were just a determined ordinary man protecting innocent people, he wouldn't know those moves no matter how heroic he was. I also would've liked to spend maybe a half hour more of character development, as the central conflict of him hiding his past from his family is what I wanted to see more.
Ugly: I can't call this a bad movie, but my pick is Naked Lunch. This is a movie with a lot to say and a lot of symbolism, but it's not for everybody. Add in the discomfort of a feature-length drug trip for myself who's never even smoked a cigarette, and it's the single Cronenberg movie that I probably won't ever return to.
+1. this is very interesting.
