I watched the thing yesterday, and enjoyed it a great deal. It did at least as good a job of compositing the threads of a very old story as "Excalibur" did for the Arthurian stories, in spite of being butchered: The original ran 184 minutes, the available version runs 132, and it is clear from the ancillary material that many good scenes have been lost; it would seem that the cuts were made just to make it shorter (with extra attention paid to scenes that played up the conflict between Christianity and Norse Paganism).
I REALLY want to see the original version, somehow. My hopes are not high. In the meantime, I recommend this movie highly, both as medieval fantasy and as visualized myth.
