Anyone else think Thor's reset-button got hit as far as this movie's events are concerned? Consider that everyone else's character got a bit more developed but with Thor his coming back is pretty much hand-waved with an "Ohhh. Odin spent a lot of money to get you here." (or something.) And then at the end the Tesseract is used to bring Thor and Loki back to Asgard with only lip service played to Jane Foster.
It seems like it was like "Uhhh... We need Thor to come back for the movie, but we also need him back stuck in Asgard at the end in order for the next movie to deal with him getting back to Jane/Jane getting to him."
I mean Captain America emerges as a leader and adapts more to life in the 21st century, Tony Stark grows up a bit more (and risks his life to save NYC), Banner gains yet more control of The Hulk and shows himself more of a hero and even Black Widow gets some development. All of this will translate into their next movies. But Thor? Nope. Reset button. He came to Earth for a few days, helped save the world, then he went back home more-or-less like nothing happened.
