The film's much less well-received by critics here, with a 63% rating on Rotten Tomatoes, but grosses here around $505 million worldwide
Thor is initially this self-righteous, holier then thou character that treats the jotunn as these violent heathen monsters which have no place in the civilised Asgard (essentially a knight templar in pagan clothing), especially after their attack on his coronation, and when Odin decides to accept many jotunn refugees displaced by violence in Jotunheim, he nearly flies off the handle, declaring he feels betrayed by him. Instead of being banished to Midgard, he's first banished to Niflheim before working his way up, slowly but surely realizing how terrible he was because of his narrow-mindedness, ad well as learning to control his temper.
Loki doesn't turn out to have started the Jotunn attack and be the villain, though its initially hinted at as a red herring.
Odin is played by Ian McKellen here, and yes, this did lead to a slew of X-Men jokes, including semi-serious "Odin is a displaced Magneto" theories
