I'd say that Thor is probably more important than the Iron Man movies, actually.
I'm not a comic reader, so, I'm not even up to snuff on SHIELD, I only know of their existence at all from the boards
I do have Thor and the two Iron Mans now, so, it's only a matter of having the time to watch that much (I'll probably tackle the Series when I finish Andromeda (Currently on Season 5, Episode 12, so, not too much left to go)
One Day I hope to be the Man my Cat thinks I am
Where are we going? And why are we in this Handbasket?
