Galifianakis, though, is the key here. Able to smash a scene to smithereens with the simplest of lines, the hirsute comic is as unpredictable as ever, yet takes director Todd Phillips’ bait to up the stakes.
The best that can be said for the third, supposedly final chapter is that it jettisons the retracing-our-steps scenario of the 2009 original and its 2011 carbon-copy sequel. There is, in other words, no hangover in The Hangover Part III.
It's an unnecessary movie, with some funny parts and a few callbacks to the original, as if visiting Las Vegas for a bit might bring back some of the original magic. It doesn't, but at least this time it seems like they're trying. A little, at least.
The Hangover Part III plays more like a caper film — “Alan’s Eleven,” perhaps — than a comedy. While Phillips ably handles the action sequences, he and co-screenwriter Craig Mazin can’t juggle both genres in the screenplay.
the third time is not the charm with this series. it was a breath of fresh air how they approached the storyline this time for the trio. Alan is the lucky man to lead this adventure and its mixed bag of funny, backtracking, raunchy moments that kind of fall flat on its face toward the end. relationships end, characters are introduced and some killed off through out the duration of the film. the montage of the boys with memories from the previous movies at the ends gives the series a proper send off. if a part 4 happens then i might throw up.
This movie is definitely a step up from the second film but what really surprised me about the movie is how it went for more of a crime thriller angle rather than a comedy and it impressed me I was actually entertained by this but the down fall is that when it does try for comedy it just isn't that funny and setting it in las Vegas was just so we can have throwbacks to the first movie.
