ON personal level Thor. He's one of my favorite characters and I loved how they portrayed him in the movie.
I liked the beginning of Captain America while he is is the process of getting the SSS.
I liked the very ending of Cap cause it got me excited for the Avengers.
I liked the beginning of Thor cause I enjoyed watching Thor unleashed on the big screen!!!
I also liked the ending to Thor.
I also liked how they portrayed Asgard it was just awesome to see.
I liked the supporting characters for both minus one or two exceptions.
The villains were a no contest to me. Loki was by far the better villain imo. In some ways I actually don't like how he got beat the Avengers. It was funny as hell but I felt it kind of cheapened the character some.
Hugo Weaving as the Red Skull I thought was gonna be a perfect fit, and in the beginning I thought he was gonna deliver but than he kind of flamed out as the movie went along.
