I was really curious to check this out, not only because Robert Pattinson has a part there, but also because Samuel West was there as well. I watched it between last night and this afternoon and I liked it although not to the point of being totally crazy about it.
The story is based in a Germany Myth that from where it is said J. R. R. Tolkien also got inspiration for his Lord of the Rings (and also Wagner for his opera The Ring of the Nibelungs).
