Continuity mistake: Once Spunky is kidnapped and Hunky takes off chasing the truck, you see the truck going along the road passing just some grass and one large rock on its left side. Once Hunky catches up to the truck, it cuts to a side view close up of him and Spunky's head sticking out the back, and suddenly the truck is passing a very large rock that was not there in the previous shot. The rock is taller than the truck, so it would have shown. And then it's very obvious the background is then looped as the same huge rock passes the truck every few seconds repeatedly. (00:01:35)

Continuity mistake: When Wrangler drives over the nails on the road, he comes to an abrupt stop.

(00:30:25)

Plot hole: When we first see the reanimated Sparky, his head's sewed on. While that makes him look a bit like the traditional Frankenstein monster, it doesn't make a lot of sense - the original monster had stitches on its neck because it was made from multiple body parts, but it's not like they sawed the dog's head off after it died...
Suggested correction: Do we ever see how much damage the car did?
Factual error: The movie takes place in 1987, but during the museum visit the main character is watching video from the Tiananmen Square uprising, which didn't occur until 1989. (00:52:40)

Continuity mistake: Just after Engi says "I solve practical problems," he gestures towards the camera with his gloved hand. He has his thumb on his left hand lying down across the top of the guitar. Then in the next cut, just before he leans down to grab a beer, his thumb is now sticking up straight. Also, his shadow moves closer to the truck's door handle. (00:00:20)
