Through a series of comedy events, the movie follows star hockey player Derek Thompson who has made a mistake leading him to be a full-fledged tooth fairy for a week as a punishment. Although the mockery he has gotten from his friends during his new position, he has managed to know many things about himself during this punishment.
This comedy is essentially a goofy premise with some nutty dialog and set pieces pasted onto it. But it's watchably entertaining, even though the filmmakers miss almost every opportunity for sublime absurdity.
This is an obvious labor of love for the filmmakers and their collective eye for capturing the beauty, grace and, often, humor of their many dances (with Dom and Fiona) with geometric precision....
To call Tooth Fairy a bad film is like calling star Dwayne Johnson a big guy. Both statements are accurate, but neither actually conveys the degree to which they are true.
For what it is, Tooth Fairy is probably a success; it's not particularly smart or original but it doesn't care to be. That doesn't offer much hope to anyone else.
The one element that lifts this above utter tedium is the presence of Stephen Merchant as tooth-fairy administrator Tracy. That he manages to come away with his dignity intact is testament to his skill as a comedian.
