Watch it. It kick major ass. Definitely better than the first. Obviously being a huge action fan made me all excited over the awesome fight scenes and laughing my ass off to the countless jokes about the actors.
It's the ultimate tribute, a film made purely for hardcore action fans who grew up watching "Rambo", "Terminator", "Universal Soldier" and "Walker: Texas ranger". It's the "Avengers" of action films, and the heroes don't need no stinkin' costumes or superpowers, just big fucking guns.
Oh, and Van Damme is the perfect choice for the villain. He is so evil you can't help but love him.
