Is the new RAMBO movie really violent, my kids wanna go see it with their dad?

The fact that it's a Rambo movie should tell you everthing. Having seen it myself, I can say for certin, OH YES IT'S VIOLENT. The begining isn't so bad, but once it gets going, "Let the bodies hit the floor." (title of a song from Drowning Pool). Can't discribe it better than that.
