This movie is very funny in some aspects, however it's very hard to laugh or enjoy in comparison to Happy Gilmore or Billy Madison. I really loved Adam Sandler, however any movie made after Billy or Happy just seemed to lag off really badly, (i.e. Little Nicky, Big Daddy and various others)
I wasn't too thrilled with this one, except Kathy Bates, Blake Clark and Henry Winkler pretty much saved it from drowning (bad pun I know) in its own title.
I'm kind of disappointed with this movie, but I wouldn't say not to watch it or buy it because if you love stupid comedy like I do, then you'll like this. I'm more apt to rent it rather than own it (if I didn't own it already)
