I'm writing a review of Avengers AOU

I liked it, I nitpick a bit, but if you like action and some fun characters, this is your movie, Tony isn't as bad as the previews made it seem, and they don't make the mistake (like countless Batman films and StarDrek into Darkness) of dividing the villain role into mulitple players. Ultron's the baddie, full stop.

there is also a refreshing bunch of sequences showing how the Avengers do their best to help people, and despite lots of destruction, they save civilians and are shown doing so, consequences aren't handwaved away.
