I liked it.
The way Jane stumbles into the main story is pretty random.
The convergence of the 9 realms was pretty disappointing, effect wise. Just a bunch of flat discs hovering over each other.
I liked to see Thor and Loki in action together.
Anyone know what happened to Odin in the end?
But where's Shield? This and Iron Man 3 lack Shield, which seems pretty unusual, given how prominently it appeared in the Phase 1 movies, and eventually in Avengers.
