Expendables was fun, cheesy, but essentially expendable, as all it is is a 80's/90's action fan's wet dream of a cast come true. Pretty lousy everything else, though. I'd take some of the classic 90's Van Damme or Stallone over that movie any day (doesn't mean I didn't have a blast at the theater).
Actually, considering Van Damme and Stallone films, I take my original First Blood answer back, and now change it to Sudden Death. Nothing tops beating the shit out of a penguin.
