Men in Black III is one of those movies that, according to all accepted rules of moviemaking, shouldn't be nearly as good as it is. Here we've got the third installment of a high-concept comedy that's 10 years out from a brutally disappointing sequel. Its star hasn't been in a movie in nearly four years; its budget was astronomical; its script wasn't even complete at the time of shooting. And to top it all off, it's about time travel, a genre based on the kind of careful forethought and planning that doesn't always mix well with the looseness of a broadly appealing comedy.
But it works, somehow, and its that ability to surprise after all these years that proves to be "MIB3's" best asset.
