THE HANGOVER PART III
“The Hangover Part III” doesn’t bother to Xerox the original 2009 hit comedy, as 2011’s witless “Hangover 2” did. Instead, it heads in different, if utterly formulaic, directions. So it’s not terrible. It’s just bad.
Ditching the morning-after-the-night-before gimmick, the new film sends the “Wolf Pack” — Bradley Cooper, Ed Helms, and Zach Galifianakis — out to locate antic Asian gangsta Ken Jeong so he’ll return crime kingpin John Goodman’s stolen gold. Occasional chuckles leak out, almost all of them due to Galifianakis’s man-from-Mars line readings, but far too much of “Hangover Part III” hangs on the notion that you find Jeong’s pansy-pottymouth schtick funny, and that’s asking a lot. With a cameo by Melissa McCarthy and Justin Bartha once more playing the crew’s all-purpose Zeppo.
