When I first saw the title of this movie, I could only think about the show Metalocalypse, and the movie that Dethklok made called "Blood Ocean" Good lord what a disaster of an episode, so good.
The entire movie that is Blood Glacier is the same kind of rolling disaster. First, you're going to have to read subtitles. That's not a bad thing, it's just all in German.
Secondly the concept is so overblown. There's a virus hidden in a glacier that looks like blood, and it has some crazy genetic stuff go on.
I feel like they were trying to create a new version of The Thing, but they kinda missed the mark. This hits very heavily on the low B tier of horror though, but that's not to say it's not worth the watch. Grab a drink and a friend to trash it with and have a great time.
