Apparently the title is just Q, not Q: The Winged Serpent, which is what everyone calls it. Huh.
I like the idea of a police procedural where it turns out that Quetzlcoatl is living in the Chrysler building, but I'm not sure this movie ahered rigorously to actual procedures. I also started to have my doubts about the cops when the medical examiner claimed one victims heart had been surgically removed when the guy's ribcage had clearly been ripped open by the jaws of life or something. Comr to think of it, the religious aspects were a little sketchy as well. I think they were using a Time-Life book for reference.
I do not hold the movie's poor special effects against it. It's a low-budget movie; whaddya gonna do?
