I don't mind the low-budget special effects at all. Even the bad acting isn't nearly as bad as a lot of these lousy films. What got me was the terrible, horrible, stupid writing. I mean, I can suspend disbelief, even a lot, but not this much. You can't pretend like physics simply don't exist. The cold snap occurs at shorter and shorter intervals and lasts longer and longer each time, yet when they get to the condemned bridge, the river isn't even frozen over. But they at least tried to prepare by putting candles in the cab of the truck. Candles. Yeah, why didn't I think of that.
