Zach Galifianakis is the focus of this final installment in the decreasingly funny series. His over-the-top behavior has the other Wolfpack members taking him off to rehab…until John Goodman appears and sends them on a quest to find Mr. Chow. Instead of the “how did we get here?” scenario that fueled the first two, this one comes off as a mediocre heist. While there are amusing moments (thx mostly to Zach), the whole enterprise lacks the outrageous originality of the others.
