A friend forced this film on me a few days before she went in to see The Avengers, because she wanted to have the backstory - it was between this and Captain America. "Which one has that actor, whatshisname, Tom Hiddleston? Thor? Thor it is then."
Almost immediately I realised I had partly seen this film before, several months ago, but even Anthony Hopkins and the (then) brief glance of Natalie Portman couldn't make me suffer what looked like a gross perversion of Nordic mythology (back then I hadn't imagined Marvel got its paws on the myths). So the ridiculous raping of lore and making it into flashy, politically correct, old-English speaking human-looking aliens had made me sick of the film within 10 minutes.
The second time around, I had no escape.

My overall impressions were that Tom Hiddleston was every bit as awesome as the fangirls squealed him to be, and that Anthony Hopkins was as awesome as he always, always is. Natalie Portman was even cuter than usual. It looked like she had a lot of fun with this film.
The script was awful. I blame the swine at Marvel for the absurdity of the plot and the outrageous look and ideas. The fight scenes were poorly written too though. Thoroughly underwhelming, there was no suspense to speak of, no doubt that all of them would survive a fight that early in the film, nothing but the paced "oooh aaah look at what they can do".

The rest of the film was all about when Loki was going to appear again. The scene where he tries to pull out the hammer, at once so pathetic and so adorable in his failure, then sighs and looks up with frustration... classic. It really came through that Hiddleston played him as a villain that thought of himself as a hero.

The biggest, and somehow most pleasant surprise, was when the credits rolled at the end and Kenneth Branagh's name came up. I couldn't believe that this mediocre, philistine flick came from the director of Sleuth. A lot of things started to make sense though, especially the Shakespearian overtones and (maybe) the brilliant casting of Hiddleston. His presence and Branagh's direction (and in a way Hopkins' performance too, though it was painfully brief) won this film a whole star from me, maybe even one and a half.
