I still remember the first "Hangover" movie, I had read about it and heard good things pre-release, saw it at the cinema and thoroughly loved it. The second one was a bit "meh" and the third one whilst just confirmed is meant to "not adhere to the structure [of the first two movies]."
Hangover star Bradley Cooper confirmed with the National Ledger that a third "Hangover" movie could be coming soon. He said that the third installment should begin filming in September of 2012, and that he believes the movie will take place in California.
He told TV host Graham Norton:
I hope we'll start shooting next September. I know (director) Todd Phillips is working on the script. We stuck to the formula in the second one but the third would need to close the trilogy. I think it'll take place in L.A. and not adhere to the structure.
