One shade more violent than an episode of Power Rangers. Seriously, you don't see a gunshot or knife hit anyone. Kind of takes away from the kickassery of the series. Still an alright movie but nothing on the first two.
IMO I think the Expendables series is basically gather a bunch of Veteran movie stars and have them do some ass kicking butt. In 3 they added like newer characters and it kinda just lost that nostalgia that 1st and 2nd one had. To see some of your favorite movie stars kick ass was probably the best thing about the Expendables.
