A piece of advice: do not pay good money and waste two hours of your life watching Thor. Not on Tyr's day, Woden's day, Thor's day, or Freya's day. Not, that is, unless you are about twelve years old or have children that age who want to go see the movie.
One major problem with it is that the story focuses on a conflict in far off galaxies between Thor's people (who are alien beings taken to be gods when they visit the earth) and some chaps called Frost Giants. Humans are largely extraneous to the happenings.
A second issue is the lighting; James Cameron got it right first time; he knew every frame had to be brightened to the nth degree to make an impact after passing through the dark 3-D viewing glasses. No other director has quite understood that, and Kenneth Branagh certainly didn't get the memo.
Kenneth Branagh: he had an extraordinary talent for making Shakespeare's words understandable to wide audiences. Actors in productions of Shakespeare usually leave me trying hard to catch what's being said, though I've read most of the plays, some of them multiple times. Branagh had a rare gift. Maybe he still has it, I don't know if he's still acting on stage much.
With Thor, though, he's seriously compromised his reputation as a film-maker.
