Stop being so Moody with your critiques!
My kids have seen his movie probably 30 times. Given, it is extremely corny, unrealistic, a bit crude at times, and ridiculous. That said, the bright colors and fast pace keep them interested.
As long as you aren't a completely boring and overbearing parent, and your kids are smart enough to understand it is a bad idea to jump in a van with strangers and crash cars through lawns sprinkled with children's toys, you and your children will probably have fun with this flick.
Expect nothing and enjoy what you get. This movie becomes an addictive winner if you are light of heart and possess a somewhat inane sense of humor.
None of my family read the book. However, if you are looking for seamless continuity between book and film, have you ever found this? This film may prove a bit further off the mark than other book to film interpretations, but who cares? It is entertainment.
