First off, the movie starts with some really good action. It cuts everything else and gets right into it. The movie knows what you came for (seeing your favorite action heroes blow stuff up) and it delivers. Then we see them celebrate for a little bit, get to know them, but no too long as its time to get to the story. The movie moves quick too. It caters to those with ADD and wants to get to the next action scene quickly. There's also no romance subplot here. It hints at one, but smartly strays from it.
The most pivotal scene of the film is when we are introduced to Jean Claude Van Dam as the villain. He plays one jerk of a villain which isn't a stretch for him since he's a jerk in real life too. He basically belittles Sly and his crew while holding a hostage. This scene set the stage for the rest of the film quite nicely and you really want to see that payback they are demanding.
Sly, Bruce, Arnie, Norris, Statham, they are are all great. My only gripe about this movie is that Jet-Li is hardly in this movie. He leaves them at the beginning of the film and never comes back. I was really hoping for a dramatic return but was bummed out.
But hey, my mom and my sister both enjoyed it and I think any action movie buff would. If you grew up in the eighties loving these guys, you should definitely check out Expendables 2!
