I have to say I thought Tooth Fairy would be shit. And it is, really, but I've seen it twice already and could probably watch it again.
It's definitely a film-by-numbers, combining About a Boy (the outcast teen boy plays at the school concert and wins the popular girl) and The Mighty Ducks (the former bad man redeems himself with the help of said teen boy), plus a few other films here and there. That's not necessarily a bad thing, and as a children's movie it's quite good, but for adults there wouldn't be very much in it at all.
Except, of course, for the presence of Stephen Merchant, who is hilarious in every one of his scenes. He could definitely carve out a nice little niche as the Disney-style comic relief sidekick in big-budget Hollywood kids movies, and I'd probably watch every one. (Let's hope that doesn't happen, though.)
