I went in knowing it was going to repeat the formula of the first film. That said, it wasn't an exact carbon copy... but, it definitely was the same basic premise. It had some twists and deviated a bit from the safety of the first film a bit more.
...but, I left disappointed. It lacked the charm of the first movie - it was just missing something. Perhaps it was too pointed at times and stretched a bit too far for a gag. The first Hangover was the perfect "boys comedy" ala Animal House and (to an extent) Old School before it... H2 missed the mark.
