Ah, I really don't care about that stuff. But like I said above, the things I want to see most in the Avengers movie that takes from the Ultimates is the Cap-related stuff.
I also liked that fact that they made Cap stronger in the Ultimates. Because with Cap, I've always felt more or less the same I have with Batman. Yes, they're both peak human, but in all fairness, somebody like Spider-man should be able to waste them in a fight. I don't care how smart or trained you are, somebody who can doge bullets and pick up a car is going to be able to beat you.
Which is why I liked the fact that they beefed him up in the Ultimates, but I was also glad they didn't go too far. I don't want Superman Cap, just a superhuman Cap with slightly super-human speed and strength.
Besides that, I loved the way the Skrulls were handled in Vol. 2, and I liked the portrayal of Hawkeye.
