Just got back from a midnight screening of 200+ people, ALL of whom stayed for the credits.
This was probably the most impressive of Marvel's film canon.
The Asgard scenes that looked a bit fake to me a first... are fully depth, straight out of the comics.
When Thor battles the Destroyer... it's a Jack Kirby page come to reality.
Patrick Doyle's score is perhaps the best of the Marvel film scores: majestic, haunting and romantic.
The cast all do a impressive job, although Kat Denning's character is useless and Hopkins is phoning it in a bit at times.
If there are flaws, it's that the humor fell a bit flat at times, there's a bit of confusion over how the portals work, and a questionable absence of a couple of the comics' central characters.
But overall, it is a fantastic film. I don't know if I'd rank it above IM1, but it'll be in my top 5 Marvel flicks somewhere. I guess that means Ghost Rider will have to get the boot.
Bravo, Mr. Branagh!
