OK, I watched the first two episodes. Still want to get in some reading time (and wanna make these last!), so that's it for tonight. But the deadly sin types have started showing up. Weird.
Yeah, it takes a while to sort of figure out what's going on. The next seven or eight episodes are going to be a sort of flashback sequence to explain how the brothers got where they were in the episodes you just watched. It all fits together nicely... sigh, I just watched 7 and 8 again. 7 in particular has a lot of things you wouldn't think would happen.
Actually, I've noticed about this anime, they aren't afraid to do things that make the viewers fall out of their chairs in astonishment. Characters turn out to be totally different from what you expect; people you wouldn't think would die, die; there are some truly bizarre twists; and things just keep escalating... frankly I haven't got a clue how it's going to end. Except I don't think Ed's going to get his limbs back.
