Saw the movie. The critics have their collective head's up their asses. The movie is fun, and that is all there needs to be. Stallone said going in he was only paying homage to the action films of the 80's. On this he has hit the mark. The film is two dimensional, without apologies. Single, simple plot line. Cliches that still work. No matter what you may think, it is still fun to watch these guys have fun. For surely they did, making this film. That's enough for me.
It may be a watch at home film, but it works so well on the big screen.
