So this is what The Hangover Part III is about
Ah so now we know what The Hangover Part III is all about, not a night after the night before but an intervention for one of the characters who is clearly going well over the top, and over the top for these characters is right over there.
The trailer looks like good fun and perhaps the most interesting of the bunch for me. There's a little more weight behind the core rather than just waking up and trying to discover what went on the night before.
The fun is still there and all the characters and actors you want to see, plus a few more.
