Washington Post: Is dressing up a corpse funny? Is '80s music funny? Is blowing up your best friends funny? It depends, really, on who's involved. You need a great character to make a bad thing good, and the action comedy "MacGruber" is sadly short on great characters. For all the wacky, taboo, parodic situations that "MacGruber" plunges into, the film seems content to simply point at its hero, yell "What a schmuck!" and leave it at that.
