Tremendous fun, from the get go where it throws its cards on the table with an actually exciting car chase (a rarity in my books); the larger-than-life cinema-romantic flourishes are a nice touch, and Jon Hamm gives good deranged, with all of the principals sharp in their roles (and, importantly, all looking the part) even though some of the characters are pretty thin and their decisions sometimes implausible. And of course the drive (ha ha) provided by the music doesn't hurt. Oh and I never realised that it was the same director (Edgar Wright) behind Shaun of the Dead and Hot Fuzz, and Scott Pilgrim! All of his films that I've seen, including this one, sure have a pep to them.
