Super (2011)

This trifle about a doofus who becomes a costumed superhero, even though he has no special powers, might have seemed funkier before Kick-Ass. Yet the movie (Super) is written and directed by James Gunn (Slither) with a certain whimsical black-comic flair. When Frank (Rainn Wilson) loses his wife (Liv Tyler) to a drug dealer (Kevin Bacon), he reacts by turning himself into the Crimson Bolt, a red-clad vigilante who defeats criminals — and other annoying people — by hitting them in the head with a wrench. It's really a one-joke movie, but the joke is a good one: Frank's ''crusade'' is just a geek's screw-loose revenge, which Wilson, digging into the character's misery, makes oddly sympathetic.
