Continuity: In the shot where we see the bar (for the very first time) they are going to, you can see the background is flat, kind of like the building is on a flat area of land with nothing behind it.

Factual error: The Abilene, Texas courthouse should read Taylor County Courthouse, being that Abilene is the county seat of Taylor County, Texas. All Texas courthouses are named by the county they are in.

Plot hole: When Seth's piledriver gives out during the climactic fight, there are many vampires in the background politely keeping their distance while he tries to restart it.
