Continuity mistake: Michelle ends the phonecall in her car at 6:27pm. When she regains consciousness in the bunker it's 6:29pm. Either she was retrieved from her crashed car, taken to the bunker, chained up and hooked to an IV in 2 minutes (impossible), or she's been unconscious for exactly 24 hours, which would be a sign of a serious brain injury (with no other symptoms). Either way something's not right.

Continuity mistake: Throughout the movie, fire axes seem to be the weapons of choice. Only two fire axes are used, but they appear recurrently. In the very first use, the protagonists grab fire axes to butcher the monster called Beverly. Blood and gore go everywhere; yet, the axes emerge from this bloodbath with no blood or gore on the handles - they're virtually pristine moments later. The axes are used again and again, right up to the ending, and blood comes and goes from the axe handles seemingly at random.
