'The Hangover' giveth and 'The Hangover' taketh away.
The first 'Hangover' made Bradley Cooper, Ed Helms, and especially Zach Galifianakis stars, and it elevated Todd Phillips from middling Hollywood director to name-brand comic auteur. But in the film industry, success that surprising and enormous demands more success; the beast must be fed. But as 'The Hangover Part 2' and especially the new 'Hangover Part 3' prove, it is very hard to make a good sequel to a truly original idea. 'Part 2' went the rehash route, recycling the plot of the first movie so brazenly you almost had to admire its chutzpah. 'Part 3' finally breaks with the formula a little (SPOILER ALERT: there is no hangover), but still doesn't produce anything even remotely worthy of the first film.
