i agree that the basterds didn't have enough screen time, but i still really enjoyed the movie, and like for most of his movies, I liked the dialog in it, which most people don't.
I enjoyed the dialog, but it should have been split up more between scenes. For instance, the scene when they're playing that card game. It dragged on and on, and all the other characters in the story weren't even seen for like 20 minutes.
The ending wasn't as satisfying as it could have been, either. Overall GREAT movie though.
