There was a song that began, “The party’s over. It’s time to call it a day.” Clearly, the people involved in The Hangover Part III didn’t get the message and tried to keep the merriment going. They failed.

In 2009, The Hangover was a funny film with some silly stuff. Set mostly in Caesars Palace in Las Vegas, it provided lots of laughs and plenty of raunch. In 2011, Part II moved to Bangkok where it got more outrageous and less funny.

In Part III, there are some smiles in what began as a very funny franchise, but they are offset with some really ugly stuff. For example, it begins with Alan (Zach Galifianakis) driving on an LA freeway hauling a giraffe behind his car. You can guess what happens when he comes to an underpass. It is graphic and ugly and one can only imagine the reaction from PETA but one cannot imagine why a filmmaker today — in our politically correct world — would even put this in a movie.

Co-writer/director Todd Phillips, whose work before has brought so much fun to the screen, falls flat here.

Up next, after a death and a humorous (yes, it has a few funny moments) funeral, Alan’s family and friends — Phil (Bradley Cooper), Stu (Ed Helms) and Doug (Justin Bartha) — decide an intervention is called for. When it is done, they set off to bring Alan to rehab in Arizona. Of course, they don’t make it.

Along with way, they run into Marshall (John Goodman) who sends them to Tijuana to bring him Mr. Chow (Ken Jeong) and the fortune in gold he stole from Marshall.

The guys — the so-called Wolfpack — winds up in Las Vegas and the ugliness continues. Locals will likely find some amusement in the scenes of Stu driving south on Las Vegas Blvd and running the red light at Flamingo. But that amusement will come only from familiarity with our city. Otherwise, it’s not funny at all.

Heather Graham is back as Jade, the hooker with the heart of gold and Melissa McCarthy is a bright spot as a woman who runs a pawn shop in Las Vegas.

At one point, Alan says, “We can’t be friends anymore. When we get together, bad things happen and people get hurt.” Mr. Chow responds, “Yeah, but that’s the point! It’s funny!”

Well, it’s not and it’s time for everyone involved to be cured of their hangovers.
