I saw this last week and throughly enjoyed it myself. Sure its not as good as the first but you can say that for a heck of a lot of sequels. And sure its not as violent as the comic but I suppose I was hardly surprised they didn't show the Motherfucker gunning down a bunch of little kids.
Like the first one Hit-Girl stole the show, I just wish it'd been made a year or two earlier as it does work better when she's actually a little girl rather than a teenager. But hey, she still had one of the greatest lines in any film ever IMO
I think I must have laughed till the end of the movie at that bit.
