The only reason Hollywood makes sequels and three-quels is because they’re presold — meaning they’re easy money — so all I have to do is type the words “Hangover Part III” and you already know if you’re in the ticket line or you’re out of there.
If you’ve seen the stunningly mirth-free trailer, chances are you’re out of there. But this third go-round for the “Wolf Pack” doesn’t bother to Xerox the original 2009 hit comedy, as 2011’s witless “Hangover 2” did. Instead, the new movie heads in different, if utterly formulaic, directions. So it’s not terrible. It’s just bad.
