Don Coscarelli's swords 'n' sorcery flick plays like Conan meets Tarzan. It's a great-looking movie thanks to the cinematography of John Alcott, who also worked with Stanley Kubrick on multiple occasions. Production values, while clearly modest, are at least a step or two up from the various genre entries produced by the Italians and Roger Corman.
However, once you strip away the nostalgic guilty pleasure value of this endeavour, it's clear that there are problems here. The two-hour runtime is overlong, Marc Singer couldn't deliver dialogue convincingly if his life depended on it and the overall tone is uncertain whether to aim at children (the cutesy animals) or a more adult audience (some nudity and grisly moments). There's also an uncomfortable bit of rapeyness, albeit nothing on the level of the following year's Deathstalker.
Still, it's passably entertaining.
