(R) ★★☆☆☆

Well, this isn’t that far removed from Bridesmaids, is it? Four friends have reunited because one of them is getting married. There’s Regan (Kirsten Dunst), the icy thirty-something professional at a loss as to why she isn’t married yet. There’s dizzy, loose Katie (Isla Fisher), booze-fueled Gena (Lizzy Caplan) and, of course, Becky (Rebel Wilson), the bride. Cue the enthusiastic cocaine snorting, f-bombs, abortion jokes and mayhem. It’s been done, and this movie’s transitions from silly to “serious” don’t work. The filmmakers just don’t seem to deliver.
