You're right; it is worth a watch. It's quite amazing that something of such high quality could be made on such a low budget.
It takes a few liberties- Taurdal, capital of the Chieftain of the North, is West Stow- but the quality of acting is incredible, and the film as a whole is great. Don't expect the grand battles of the official movie, though this is understandable.
All in all a great film, and quite watchable as a standalone.
I'm not wierd, it's you!
