Well I just got back from watching the Avengers...
What a fantastic sequel.
They got some much right it's incredible.
I'm really impressed with the fight scenes, especially those for Captain America, Hawkeye, and Black Widow. So these characters don't really have super-powers but Marvel was able to pull of this look and feel of them being more than human which is how the comic versions of them feel.
The Romanner love plot was bleh...it served as a filler to the story.
Quiksilver and Scarlet Witch came off well on the screen. Minority stake in terms of screen-time which served their characters pretty well as they should not get more screen-time than the actual avengers. I do wish their was some nod to the high evolutionary though seeing as they may make a Warlock movie in the future and that reference to him would have been nice.
I expected to see reference to more characters - Black Panther, Namor, Ant-man/Pym, etc. so I was disspoint a little.
However the real stars of this thing imho are Ultron and Vision. Hold **** these characters were translated so well for the screen. Couldn't have been happier with how they came off.
The whole breakage of the shells to reveal the gems was a great nod as well.
