OK, this movie was pretty good, and as I said, under two hours. I really appreciate movies like that these days. It's still a little too long, but maybe only by five minutes. I watched the second Captain America movie as well, and that could be trimmed by a good 20 minutes (I'll review that one later). The movie had a fair amount of humor, which is always a plus for superheroes. Good thing Marvel/Disney seems to realize this now.
The story has Malekith of the Dark Elves wanting to use the "Ether" to cleanse the Nine Realms, which he can only do when all nine realms like up. Sounds like a crisis of realms to me. Jane Foster somehow absorbs the "ether" and of course, that leads to all kinds of trouble
Rene Russo as Frigga, and was taken aback by what happens. But she sure got a great final scene in the movie.
Jaimie Alexander looks like a woman, and a warrior goddess. Tough luck, Jane.
So I enjoyed this movie. Late to the party, I know, but it's worthy of your time.
