Caper is a webseries up on Geek and Sundry's youtube page. The series is written by Amy Berg and Mike Sizemore and features 4 superhero roommates who decide to pull a heist against an evil mega corporation to help them pay rent.
The characters are quirky and all of the 'super' scenes are done as animation clips (which is a clever way of avoiding the cost of special effects). There are also some famous SF actors making cameos.
Here's the first episode to get you started, and their playlist to help you continue.
