If you expect a rigid storyline that hits all the stereotypical beats for a fantasy movie, you will not like this movie. Think of this instead as a semi-structured collection of concepts.
There is a beginning, a middle, and an end.
There are two main leads but neither of them could be described as “heroes” despite the fact one is from a magical dimension, has a magic bow, and has been sent to destroy the evil villain. It is mildly bewildering but ultimately delightful that midway through the movie, he actually makes a credible attempt to simply leave the whole thing.
At the time I watched it, I was startled and a bit confused. If I’d written this review then, I think I would have been very critical. But after some reflection, I think that I rather admire it. It has the courage to do something convincingly different and refuse to apologise for it.
It is from the early 80s and reflects its origins. Female characters are either extras or the extraordinarily sexy and evil villian. The special effects stop just short of being painful. Some of the side quests are by now quite typical fare for your regular D&D collection of adventures.
If it were remade now, with the same kind of lavish attention as 300, for example, and a couple of little tweaks here and there, I reckon it’d be outstanding. Seeds of brilliance all over the place. But that’s just what I think, so if you don’t agree, shrug and move on.
