The thing about Thor is, they completely underplay him. I mean, aside from Hulk (which I personally liked), he is a GOD amongst human heroes. I don't think most people sit and consider this. This is the philosophical dilemma all Superman movies have had.
If Marvel played it smart, they would ignore the fact that this is just a prequel, and advertise and spend a LOT on this film, because it SHOULD be epic, instead I'm seeing that this will be another fun movie, that may even bomb if they don't find a chemistry between the modern world and Asgard.
Thor has… like Superman and Hulk all the material to be a movie about a meaningful "Clash of the Titans." If you just read JMS's Chapter 600 where Thor faces ______ .. you get what I'm talking about. That was a battle, that was deep storytelling, and masterful usage of Loki, who is not supposed to be some "Riddler," but the god of trickery and mischief.
Sorry for ranting, but Thor is one of my favorite heroes, especially during JMS, and I know they'll pull a Hulk.. not to say Hulk was bad, but it could have been SOOO much more with the premise it had.
