Usually when I watch a comedy by myself, I question whether it's as funny without a partner to share the laughs with. This was the rare instance that the question never entered my mind. The Hangover II is nowhere near as good as the first and falls in to the trappings of Hollywood's desire to destroy anything successful with an under developed sequel and premature script. Yes, there's a few funny moments. But, not enough to carry a whole film.
Fans of the original Hangover should be prepared for disappointment when renting or buying this movie. It insults the legacy of the first by cloning it's plot and replaying familiar jokes. Seriously, stay away from this. Go watch the original again. It's much funnier the tenth or eleventh time.
