The animation was cleaner, some of the voice actors returned, but the villains at least in this episode were very bland and 2 dimensional. Also a body swap episode as your first episode is kinda lazy IMO. So to me it was just meh.
I'll say that I agree that it was rushed, ugly, and the in fighting was forces as ****... a lot of it didn't make any sense. The Hulk just jumping on the Quinjet for no reason and then Thor bashing in to him so they could crash in a damn near public area where people could get hurt was stupid.
I will say though, I didn't like the first two episodes of Avengers: EMH and they didn't catch their stride by episode 4 or so.
How many of the original creators are a part of this one?
