Oh then I misunderstood you.
Didn't really look where you come from, sorry for that.
Well it's isn't a huge difference between the mythology and the movie. I don't think people would like the movie if he didn't have armor and didn't look like a hero. I mean, at least he doesnt have clothes similar to the rest of the marvel heroes.
I like the movie, though I prefer the real version, but the appearance fits in the movie, at least that's my opinion.
