YouTube's WatchMojo offers super origin videos

[Lumbering Jack (M'odd-R8-Tr)]

WatchMojo does a lot of these, and they are great "Cliff's Notes" versions of a variety of superhero and supervillian origins.

This one covers the birth and confusion over the identity of the Hobgoblin.http://youtu.be/YCnW5jpSXxM

And here's one for Ben Edlund's The Tick! http://youtu.be/mS69LuAs1nM

In general, I find these to be pretty good recaps.
