Factual error: The bandages for Freddie's stab wounds are on top of his shirt. If he were really stabbed severely three times on the shoulder, the paramedics would have at least make him take off his shirt to better dress the wound. Freddie didn't even take off his jacket!
Factual error: Katee Sackhoff's name is misspelled "Katee Sachoff" in the opening credits.
Factual error: As we see in some of this series, Michael pins his victims to the wall with butcher knives. A kitchen knife isn't capable of holding a person's body weight pinned to a wall.
Suggested correction: Sure, it can. If it's a full tang knife jammed hard enough into a stud, especially given Michael's seemingly superhuman strength, it could definitely support a body.
No. There wouldn't be enough knife jammed in the stud to support a body. The average man has a chest depth of about 10", and Michael is shown using regular-sized kitchen knives, which are typically 6-12" in length... and that includes the handle. Honestly, none of the knives Michael uses would realistically be long enough to go all the way through a man's chest, let alone embed themselves into the wall behind the victim. So it's 100% impossible as depicted. This is simply a suspension of disbelief situation where the filmmakers knowingly included something completely unrealistic and impossible because it was a great visual. So it's 100% a mistake... but it's a cool mistake because it looks great on camera.
Factual error: Michael Myers stabs the first two knives through Rudy - they are very small and not very strong knives, but they manage to hold Rudy's weight upon the door. (01:04:05)

Factual error: The rat that Michael Myers supposedly ate that the redhead touched was able to move and squeak despite its lungs being torn out of its body.
