I was so torn up about Agent Coulson, because I find his actor so very likable, but I didn't really like the way that his death was supposed to ~galvanize the group~. As beer_good_foamy pointed out, why couldn't all of the other innocent people who died have done that? Especially considering that several of those people had no relationship with Coulson. I will miss him loads in future movies, though.

I wish we had gotten to see more of Clint Barton instead of zombie!Hawkeye, but that just means we need the prequel EVEN MOAR.

Agreed.

I think it's really, really too early to say what Mark will think about Buffy and Spike together. We'll see, I guess.
