1st - classic. 2nd - OK. 3rd - the worst.

For me the Hangover Part 3 was simply the WORST installment of the hangover trilogy. It made me realize just how great the first two hangovers were because the ideas were just so much better and funnier.
The first Hangover is not the funniest R rated comedy I've ever seen, but the whole idea of three groomsmen losing the groom during a bachelor party in Las Vagas was such a clever idea that lead to a great plot and tons of fun that made it such a damn good movie.
The Hangover 2 was just the same rehash as the first, but what made part 2 so good is that it took the same idea from the first one and put different twists into the plot that at least made an attempt to make it as good as the first one. In fact, I thought it was almost just as good as the original.
The Hangover 3 on the other hand was nothing more than a conclusion film that told the audience that this was the final adventure. We all knew Phil, Stu, and Allen couldn't possibly lose a bachelor party friend for the third time, so what we got here was a darker more action- themed Hangover movie. Hell there's no bachelor party or anything to get hung over from in this one.
What happens is that Chow escapes from prison after being captured in the 2nd one, and heads back to the United States. Meanwhile Allen's father passes away and his friends and family decide its time to have him put in a mental hospital after he stops taking his meds. Phil, Stu, Allen, and Doug on the way to the mental hospital get run off the road by a group of thugs and are captured. Marshall the head thug, tells them how Chow stole a large amount of gold from him during a heist, and because they are close friends to Chow they have to bring Chow to Marshall or else they will kill Doug...again... And that's basically the short intro summary to the Hangover 3. Boy that all sounds like it escalated quickly didn't it?
Everything else from that point on is nothing more but boring R-rated comedy humor that drags on. The Hangover humor is just dry and old by now. I got a few chuckles and that was it while I was laughing much harder at the other two movies. The other two hangovers were so much more fun and exciting while this one was a more epic-themed action flick that was too predictable. Chow was actually just starting to get old in this one to the point were he was actually annoying. He was funnier in the other two because he just played one of the minor characters. In this one, he is an essential character to the plot who you see all the time and all the dialogue he says is just so Unfunny. Who ever wrote the script for Chow was really trying to push some desperate laughs. They should have just called this movie ''The Changover part 3.''
In conclusion, if you enjoyed the first two hangover movies, chances are you will be quite disappointed by this one.
