Whatever happens in Vegas slays in Vegas? They wish.

Maybe the best time to sit through the bachelor-party-gone-kablooey comedy, The Hangover, is during a hangover. That might make it easier to overlook all the narrative omissions and juvenile excesses in a movie the guiding principle of which might well have been that getting a wince, a groan, or a raised eyebrow is just as good as getting a laugh or a smile.
