Deliberate mistake: During the final battle, when Ash is driving around in his car with the giant fan mounted to the front mowing down enemies, some of the evil skeletons he runs into aren't moving at all for several seconds before being hit. This reveals that the were just props designed and set-up to be run over for the effect. Additionally, the first two sets of skeletons he chops up in the fan are the exact same skeletons shot from different angles. (You can tell from the distinct way the one skeleton's arm comes off and ends up on the car's front).
