Diminishing returns.

Rating: 5/10 (14 December 2011)

Same exact concept, mostly the same hijinks, but not nearly the same payoff. That's The Hangover Part II in a nutshell.
This time, the "wolf pack" ends up in Thailand for Stu's wedding, and once again things go horribly wrong and an entire night (and another person) are lost in a haze of substances, carnage, and bad behavior. And just like in the first movie, most of Part II is spent with the guys trying to piece together what happened the night before, get everyone back safe before the wedding, and just generally not die.
This is a pretty unnecessary sequel, and it shows. It's just not early as funny as the first movie, the characters are less likable and more annoying, and the whole thing just feels stale.
