only in age of thunder that thor disrespect odin. every other writer has written thor with respect for odin. fraction's thor is much more rebellious and spiteful. he calls odin an old fool and stupid. just like in the age of thunder. his thor is not bright and has not learned ANYTHING from his enlightment during the previous ragarok. as we the reader see thor not being the thor that we've known lately, fraction is making a point in his writing that this is the thor he wants to represent. the angry and not so bright thor.
i really don't know what fraction is planning for thor in the coming future, but i hope he has a clear vision to it and hopefully he'll explain what the hell he's trying to do with him.
They're trying to make Thor appealing to the type of kids who are typically Hulk/Wolvie fans, ie., those who only care about RAGE! GRRRRR!
