To say I am excited for this would be a gross understatement. It's like the excitement of one hundred children on Christmas Morning. And after seeing Iron Man 3, the best of the Iron Men (I loved Trevor!), that excitement is at more of a fervor.
Marvel is also teasing an extended version of the trailer over on the Agents of S.H.I.E.L.D. website. If you want to help unlock it, go tweet #CoulsonLives.
