Thor: The Dark World II

Highlights:

scenes in the realm of dark elves, filmed in Iceland;
also, scenes in London with action alternating between them;
interaction between a small group of mortals and the Aesir;
Thor temporarily separated from his hammer having to travel by Underground;
- and falling past the windows of a London office building;
good visuals for Asgard;
a reference to Odin's father;
as before, a well-cast Odin, Thor and Loki;
Loki's perpetual combination of being hard done by with irreconcilable malice;
a former Doctor Who unrecognizable under his dark elf make-up;
the strong sense of a continuing story both for Thor and for the Movieverse.

Any bad points?:

"the aether" is not the best name for the force of darkness;
Thor refers to himself as a man.

Thor: The Dark World

The DC multiverse had the Crisis on Infinite Earths;
Michael Moorcock's Multiverse has the Conjunction of the Million Spheres;
now, the Marvel Movieverse has the Convergence of the Nine Worlds.

Everything changes but the story continues. The Original Darkness returned to destroy the Light in Alan Moore's Swamp Thing, where it was recognized that Light and Darkness interpenetrate: "Where is evil in all the wood?"

There are two unexpected deaths in the film and at least one of them seems not to have happened or to have been reversed, of course.

A dweller in Asgard, a so called "Asgardian", is a god, an as, of which the plural is Aesir, so this is the word that should be used. Vanaheim also appears in the film. Its inhabitants are the Vanir, the other Northern pantheon.

Loki appears briefly as another superhero, thus, effectively, allowing an appearance by that hero in this film.
