This has got to be the worst "children's" movie ever made. I can't believe that Mike Myers was a part of this piece of garbage. It's painful to watch--ridiculous humor (and not the good kind), totally inappropriate language and inferences for children to hear, it's shot very dark and ugly.
Shrek managed to include adult type humor that was both clever and fun without being inappropriate for children. For example, the cat says "Judas Priest" several times, makes a crack at a garden hoe, saying "You dirty hoe!", etc. Sorry, not for my four year old.. All of the adult humor, and it's horrible even if you watched it without your kids! Luckily I rented this instead of buying. Save your money!
