Very good, not fantastic, but very good.

Alright, this held my attention through the whole film. I liked the quiet parts more than the noisy ones, actually.
The cast is great, Wedon gives them quipy dialogue throughout. The revelations of the characters (things we didn't know about some of them prior to this installment) were I thought its biggest strength.
Won't reveal any of them here, but suffice to say, sometimes it's nice to see under the armor, if you take my meaning.
I liked it, but what kept me from loving it? Probably the fact that they're essentially going after another big baddie and his countless minions, who are easily dispatched, as they were in the first Avengers. I had hoped the threat would spin what we've seen on its back, but alas.
