Either DC Comics and Marvel have put aside their differences to give us the single greatest Bollywood dance number, or this is the most unabashed copyright violation of all time. Regardless, the dance is a CLASSIC. The "Spiderwoman boogie" deserves a place between Gangdam Style and the Stanky Leg in the dance craze canon.
If you came for the dancing, buckle up for the action. Note the deeply-technical CGI wizardry that would one day inspire Zack Snyder's "Man of Steel."
