In arguably the best movie of 2012, Joss Whedon weaves in the separate tales of some of Earth’s Mightiest Heroes into one Helluva an action-packed tapestry.  The Avengers is a true testament to Whedon’s ability to work with an ensemble while giving each character his or her own chance to shine and to be vulnerable. One notable stand-out is the complexity Mark Ruffalo brings to Bruce Banner/Hulk. Come for the action, stay for the snark.
