Stu (Ed Helms) is the one tying the knot this time around with Lauren (Jamie Chung) much to her father's disapproval. Inspite of Phil's (Bradley Cooper) attempts to persuade him to have a bachelor party; Stu remembering the events of Vegas refuses and invites the "wolf-pack" to simply attend the marriage instead. However a simple beach bonfire drinking session results with the trio waking up in the morning without any memory of what happened. Alan's (Zach Galifianakis) head has been shaved; Stu has a tattoo like Mike Tyson and Teddy (Mason Lee), Lauren's prodigy kid-brother is missing. To compound their troubles further they have no idea where they are the shit really hits the fan when they find Teddy's severed finger. Thus begins the journey to find out what happened the previous night leading to a cocaine-snorting Chow (Ken Jeong), a chain-smoking drug-dealing monkey, transvestites, monks, mobsters & other assorted weirdos. They have one day to find Teddy and get back in time for the wedding, sounds familiar?
I cant blame the makers for essentially recreating the first part in a different setting cause there is little you can do with the basic concept of "Dude what the hell happened last night" plot-wise. Where the movie disappoints is the quality of humour which strives to be simply gross at every given opportunity with all the kind of Neanderthal & juvenile jokes possible and to compound the problems further you can see every joke & plot twist coming at you from a mile away. I won't deny that I laughed at times (the scene in the monastery for instance) but few and far in between. The predictability of the situation kills much of the fun element which the first one had.
The exotic Thai locales are a sight to behold early on and towards the end but the moment the action shifts to Bangkok, the cinematography takes a turn for a gritty, dark look.
Zach Galifianakis is still the star of the show, with his quirky 'Alan'-isms but is getting stale pretty quickly with him having played almost the same role in every movie since the original. Bradley Cooper benefits from playing the hunk while Ed Helms is less than capable of carrying the movie on his shoulders alone. I can imagine someone like Steve Carell doing a far better job than he does. Justin Bartha inspite of not being at the receiving end doesn't get to part of the action.
'The Hangover Part 2' is a cash-cow and has no reason to exist other than the fact that the first one made a ton of money. If you absolutely loved the first one you might be only perhaps slightly disappointed with this one inspite of it being a total rerun of the original. The ribald humour is gets tiresome with its constant attempts to gross you out at every turn; either way most people are going to watch this movie and its going to make a mini-fortune which will essentially lead to 'The Hangover Part 3: Alans Wedding'...oohh!!! the thought makes me shudder.
