This was a good film. Low budget, but it still comes out as a decent creature feature. The law was a bit slow to figure out what they were after and even slower to track it down. I always hate that in movies. It makes no sense to me why people think that is suspense. It deteriorates suspense because it isn't realistic.
I don't understand why they threw in Shield's personal life either. It would have been better if he was cast as an older and more experienced sheriff with nothing to lose. Maybe he should have had a drinking problem. It didn't add anything to the story besides him having a family that he doesn't want to see die under his care. But that doesn't make any sense at all given events in the film.
The creature wasn't entirely unique either. I got a very heavy feel of Dean Koontz's "Watchers" in there as inspiration. I think if you took Koontz's story, mixed it with this movie's plot, renamed it to "Stalkers" and added more scenes of the creatures in them it would have been a better movie, and Koontz would have a better book with this movie's plot.
"The New Daughter" with Kevin Costner was a lot better, by miles, and they used practical effects that beat this film's CGI by lightyears. And that was also based on folklore in its own region. The two movies are apples to apples, in my opinion and I need to give the medal to Costner and the Mound Walkers.
