[spoiler]Seriously, I was hoping Hawkeye wouldn't die, but killing off Quicksilver surprised me too. I figured he'd be around for at least one more movie so we would have time to really start to like him first. Overall, I think the movie was great, though I was hoping Bucky would show up. I'm glad Maria has a larger part than she used to, as I find her quite entertaining.
I wasn't distracted by Hulk x Black Widow, but I was sort of expecting it.
Ultron himself was surprisingly funny. I don't usually expect that out of the villain, particularly when said villain is AI. I was sad when it looked like he killed Jarvis, though.
The best parts, in my opinion, were the scenes involving Mjolnir - first when no one else could lift it (except Cap almost did and Thor panicked for a moment), then when Vision picked it up like it was nothing and they all just stared at him for a bit.[/spoiler]

I might wake up early and go running. I also might wake up and win the lottery. The odds are about the same.
