I'd say a downright perfect movie. Only thing that would have made it even better is if they left it and refrained from doing sequels strictly for money.

A personal favorite! So funny!

Three men. One trip to Las Vegas. One big hangover where they don't know where they are or what happened. One of the greatest box-office hits in 2010, The Hangover is full of comedy and plot to get the audience involved and curious. The movie is like a winding path, going through the adventure that was taken in Las Vegas. With its wacky characters and twists, The Hangover succeeds as a great movie.

This movie while being humorous, was very spontaneous and didn't really clearly make sense until the end. Though I was slightly confused due to the events happening so fast and random, I did enjoy the jokes and the ending was satisfactory. I think this movie was definitely a good watch.

this movie franchise steals from the premises in "The Sins of Harold Diddlebock" A film with Harold Lloyd, a silent film star. If you watch is you will see all the ideas that were stolen right down t its basic premise on which this movie is named the hangover. Its a wonder there weren't lawsuits.

Hilarious movie.

Beneath all the big-budget effects and frantic adult language this is really the cinematic equivalent of an all-night kegger aimed squarely at the college fraternity crowd. The only potential laughs came at the very end with the discovery of a lost digital camera and its trove of incriminating pictures. In an effort to fill in some narrative gaps and explain exactly what happened that fateful night the director tosses some of those photos onto the screen during the closing credits where we’re treated to an assortment of bare breasts, a prosthetic penis (wow, unrated versions rule!), and surprise cameos from a few Las Vegas mainstays. Unimaginative, juvenile, and looking like it was slapped together overnight, "The Hangover" goes for quirky but settles for mediocre. And they never did explain where the damn chicken came from.

Total male wish fulfillment fantasy…which I guess means that males wish they could get rufied and abused for three days straight in Vegas. None of the characters are all that likeable, but the three leads do a great job, and the movie is actually quite funny.

DO NOT DRINK AND BECOME A BAD FINK

Boy am I ashamed to have this movie on my library record (hi NSA!). It was beyond horrible. Sophomoric lad humor that seems to have been thought up by aging character disordered frat boys. The only good female character was the cliche' "whore with a heart o' gold". The other women were a raging bitch girlfriend (probably meant to represent "feminists" as seen by the most craven and fragile of male egos), the bride who was definitely portrayed as having the potential to morph into "feminist" at some point in the not too distant future, and a wife who makes her man "die a little inside every day" (though the wife of the character who said this was affectionate and seriously hot-looking?). Even worse there was jokes about pedophilia, and Zach Galifianakis's character making a baby boy pretend to be jerking off (how was that even legal to depict?!) The rest was predictable and sad. There was not much talent, and even less group chemistry in the acting. The saddest actor was Mike Tyson, who can't even convincingly portray himself (too much brain damage, one presumes, from boxing or tertiary stage syphilis?). The movie itself was sad and awful, but the end sequence was icing on the whole foul pile; it will make you want to take a course of antibiotics after watching it. And please note that there is actual pornography in this part, which I was very dismayed to see, and it was not mentioned anywhere with any surprise in the media, and no warning beforehand. I so did not want to see Zach G's erect phallus being worked over by some (obviously real-life) hooker. In other words, this movie is NOT family-friendly by any stretch of the imagination. If this is what Americans think is cute and funny today, then it's no wonder the rest of the world hates us. Very depressing indeed. If you MUST watch this movie, take some "roofies" first, so you won't remember it later. I sure wish I had!!

One of those rare comedies that manages to contain originality.
