I haven't seen the trailer, but did get dragged to a showing. It's not good.
I've seen:
Conan the Barbarian - good fun, some great lines.
Rio Bravo - decent western, though I'm not sure why it's held in such regard.
MASH - a classic.
Big River Man - documentary about a boozing endurance swimmer's attempt to swim the Amazon. Fascinating material, but I don't like how the story is told and the score, in the first half at least, is obnoxiously bad.
