Shrek 3 "little bit yucky, but a bit good" words of my 4 yr old

Rating: 4/10 (10 June 2007)

My 4 yr old sons words and review of this movie are as follows:
"The frog died, and because the yucky man was trying to kill Shrek. And the pigs were trying to fight the yucky guy which was really funny."
Now I watched this movie with my children and to be honest they weren't that impressed they preferred to watch Shrek 2, go figure. I myself was of the same mind as my children, wasn't bad and wasn't great sort of hanging out in the middle there.
What I wasn't impressed with however is this movies blatant use of sexual innuendo, passed off as jokes and gags. What demographic are the writers aiming at, there are a few areas in the movie where i was just thinking "What The?"
