The Hangover Part III is more like "Beverly Hills Cop," a generic crime flick improved by comical touches that shouldn't fit the proceedings.

As "Hangovers" go, Part III isn't challenging or unpleasant, just instantly forgettable. It won't take much to sleep this one off.

Tonally a complete departure from the rest of the series, which is at once laudably brave and disappointingly unfunny.

Ditching the hangovers, the backward structure, the fleshed-out characters and any sense of debauchery or fun, this installment instead just thrusts its long-suffering protagonists into a rote chase narrative, periodically pausing to trot out fan favorites for a curtain call.

Young viewers looking for unbridled raunch will be sadly disappointed, and so will other moviegoers expecting more than a few wan chuckles. This picture is like a brightly colored balloon with all the comic air seeping out.
