Hugely entertaining and utterly ludicrous. Go knowing as little as you can.

Gory farce with two enormously likeable leads. The premise gets a little worn as time goes on, but it's good fun with plenty of genuine laughs.

Me, for the first 5-10 minutes: This is sort of familiar and lightweight.

Me, for the rest of the movie: This is wonderful, and I'm a jerk, and shut up there's just something in my eye.

Every bit as warm and charming as I'd hoped, thanks to two enormously charismatic leads - Jean Dujardin's smile is remarkable, and Bérénice Bejo is the most adorable thing there ever was. I wasn't entirely swept up, but left with a definite spring in my step, mostly due to the joyful and immensely satisfying ending sequence.
