Like in the first Hangover, the raunchier sequel starts with most of the damage already done. This time it's Stu (Ed Helms) who's getting married, and the “wolf pack” (Bradley Cooper, Zach Galifianakis, and Justin Bartha) heads to Thailand for the wedding. Then comes one crazy night in Bangkok that nobody can recall.
The first movie's baby is replaced by a monkey, and 2009's breakout star Galifianakis gets more screen time; otherwise The Hangover Part II is pretty much the first movie with a new setting: The guys pass out, someone is missing, and Stu again wakes up with his face altered (this time it involves a Mike Tyson-style tattoo). And once again the guys try to unravel very fuzzy clues to piece together the wild night they can't remember (Ken Jeong and Paul Giamatti have something to do with it).
There are some funny scenes here, like Stu's unfortunate strip-club experience, but most of the plot and best jokes are recycled from the original movie. --Michael Gallucci
