My biggest problems with this were ones of logic. I kept wondering how, if the Creeper only comes out for 23 days once every 23 years, and seems to spend all day every day killing folks for those 23 days, how he can build all the booby traps in his truck, or even learn how to do so, or custom-make his weapons, or somehow acquire bulletproof tires and windows, and so forth.
Of course, if the movie were better, I'd get swept up in it and forget about these problems. Or care about them less, anyway. The movie isn't terrible, but it doesn't feel like there's much of a reason for it to exist. And it's set between the first and second films, which means nothing really big can happen, and most of this one feels like it's just marking time until the story from Jeepers Creepers 2 starts.
