SPOILER WARNING: Since the film has been out for a while (as evidence by my being 20% of the cinema audience) I don't see any reason to restrain myself.
The Mighty Thor in London
I rather like that the “Midgard” bits of the film are set in London. London does seem to attract the godly type of superhero these days what with Wonder Woman moving there a couple of years ago. The Greenwich Meridian seems to be the centre of the universe, which is a bit odd but rather sweet.
The one thing I came out of the first film wanting was to see more of the Nine Realms. We got a lot more Asgard in this film, which makes sense, since the first film was about Thor in Jane's world this time we see her in his. She even meets his mum (who is absolutely hardcore, by the way). Natalie Portman wants out of the series after this point, which I don't blame her for as her character has a lot less to do this time round. Still, it might not be a bad thing to drop Jane here, now she's seen Thor's world there's nowhere else to take her really.
I hope they keep Darcy, though.
How to waste Christopher Ecclestone in one easy step
Christopher Ecclestone is a brilliant actor, I think most people will agree. He has a great deal of charisma, an imposing physical presence and great delivery. However, a lot of his power comes from his voice and so having him speaking elven gibberish for half the film was a mistake, there's no other way to put it.
Hogun the Grinning
They wrote him out because the actor was only available briefly, which I can understand, it was a job to do and it was done as well as could be expected.
Guardians of the Galaxy looks fun
The traditional tease for the next film saw Sif and Volstagg delivering the aether, aka the red Infinity Stone, to the Collector who was Benicio delToro acting bloody odd. He also had a bloody odd bright pink minion lady. The acting choices were jarring but I suppose it'll make sense when we see these characters in context with the film they're actually from.
It also makes sense of Thanos' cameo at the end of Avengers Assemble if the Infinity Gems are on the table for this phase of the films. I wonder if there are any other artefacts beyond the aether and the tesseract that might also be “Infinity Stones”.
Chris Evans' cameo
I loved that bit: Chris Evans playing Loki pretending to be Captain America. “Let's have a bracing conversation about truth!” and “Gee, fella!”. You can see the actor having a ball playing the straight aspects of his character for (louder) laughs than normal.
It's all about Loki
You wouldn't have to follow the comicbook sites to know which character from this film is getting his own comic. With Hogun off the board the other two Warriors Three and Lady Sif got a bit sidelined in favour of Loki. Ray Stevenson got some good lines as Vostagg but it really was all about Loki. Which is no bad thing, Tom Hiddlestone plays a great anti-hero/villain and his imprisonment in the earlier half of the film gave him a chance to really convey the character's psychology in ways his previous two turns didn't.
And that ending was a great tease for the next film whenever it's due to come out. 2016 I assume.
The trailer for Captain America: The Winter Soldier looked amazing. They seem to be going to a Captain America vs. SHIELD idea. 47 Ronin seems interesting but I hope there's more reason for Keanu Reeves' headlining role than Hollywood not being able to handle non-white leading men even in a film clearly about an Asian fantasy world (I did actually think it was the second Last Airbender movie when the trailer started).
