Guardian of the Realm has surprisingly good production quality and special effects considering its low budget. It is the story of a couple of demon hunters who are about to face the biggest challenge of their careers - an ancient demonic power has escaped hell and rallied a small militia of demonic minions at a local night-club.
The overall cinematography and effects is comparable to the TV-movie work of the Pre-Battlestar Galactica Sci-Fi Channel, though the cast isn't quite as talented as the typical Sci-fi channel cast. Most of the effects involve people morphing into demons and some well-done wire work. The martial arts choreograohy is also pretty good.
Thankfully, Guardian does not take itself too seriously. Though Glen Levy and a few other cast members are competent actors, the directing and editing do fairly little to help them convey their talent. Many of the performances are somewhat tongue-in-cheek, and lend the film a cheap, exploitation B-movie feeling. This becomes more and more clear as the film approaches its utterly absurd climax.
This is definitely not a must-see, and whether you leave it on during a random channel-surf late at night is entirely your own decision. I suspect that most people will be LESS entertained by it than I was.
