I liked it and I didn’t like it.  First off, let me go over what I didn’t like…

I hated the stupid flying aircraft carrier that turns invisible.  Okay, the Carrier was cool to a point… that point being right up till the moment it started to lift off up out of the water.  That suspension of disbelief request by the film makers was just too much.  Then on top of it… it can go invisible.  No… I don’t think so. You have all this great technology but still can get shrapnel out of Tony Stark’s chest?  Really?
The huge amount of CGI with so much crap happening on the screen all at the same time… it gives me a headache.  This is one of the reasons I didn’t like GI Joe and it looks like the same people that did that did this.
But what I liked –  Joss Whedon’s script.  The dialog and the way he wrote the interaction between the characters was absolutely brilliant.  You have Super Heroes here, which requires a lot of suspension of disbelief already, but you have dialog that makes them human and makes them real.

I also liked how you have these super heroes with earth-bending powers… and a chick with a pair of Glock’s can keep up.  In her tight black cat-suit. Wish her hair was longer like in the last Iron Man, but still.  I liked Hawkeye too.  The actor, the lack of high collars and capes on him… I liked that.  The Arrow Head selecting quiver was a bit much… but it was still good.
