Having just come back from Kick-Ass, and is a very good movie. Not on the like Schindler's List or Sophie's choice scale of the term. But on the great Schwarzenegger 80's action movies. It has violence true, and some really hideous violence. there is no getting around that. But the characters are great, and funny, and more than that they are true.  You actually believe that Dave would become kick-ass and in fact I'm thinking that maybe some other people would in his situation. Also his friends remind me a little too much about some friends I had in high school.  
 
The sound track was great, the fight scenes were  some of the best I've seen in ages.  Nick Cage gave his best performance  in ages.  This is a movie you should see if you like action movies.
