It's hard to think of many, but if I had to pick one, it would be "The Incident" (1967). It's a great movie, too, a favorite of mine. It's a straight-forward thriller (Martin Sheen's first role, and possibly Beau Bridges), but it's also allegorical.
shareBody Heat is a favorite of mine and both of the main characters are despicable. Even the victim, Matty's husband is not a nice guy.
shareI always loved The Libertine with Johnny Depp.
the incident is a terrific movie. but as i recall, most of the victims are pretty sympathetic.
donna mills had a smaller role in it. the teenaged damosuzuki fancied her quite a bit.
But they also had a darker side outside of the train. None that I can remember that were likable.
shareit's been a good number of years since i watched it, and i have a very wobbly memory when it comes to things like this, so i'd put money on you being right.
it looks like there's a stream of no doubt dubious legality posted on youtube. i think i'll give it a re-watch today.
Cool.. I was about to mention something, but I'll wait.
shareGoodfellas has some charismatic characters that are interesting to watch, but I don't think any of the main characters are decent people.
I don't think you have to really root for characters in a movie to enjoy that movie, though. Goodfellas is brilliant.
