"Thor to begin with is not an interesting character. The gods of Greek, Roman and Norse mythology share the same problem, which is that what you see is what you get. They're defined by their attributes, not their personalities. Odin is Odin and acts as Odin and cannot act as other than Odin, and so on. Thor is a particularly limited case. What does he do? He wields a hammer. That is what he does. You don't have to be especially intelligent to wield a hammer, which is just as well, because in the film Thor (Chris Hemsworth) doesn't seem to be the brightest bulb in Asgard."
