I may be the only one that loved the OP
So, far I'm quite pleased with the progression of the characters. I hope we are explained why and how Thor has such great skill with his weapon, but I'm sure more background will "drip" out. Can't deny, anime always fills in those gaps with backflashes, just a matter of patience for now.
I'm looking foward to more episodes for this story, and from what the manga readers state, it should be forthcoming and not just "teenage angst"
YEAH!
