A few things I learned...spoilers ahead

Movie was cool, but just like other horror movies, I have to poke some fun with them:

1. A convention can take up all the hotel space in the small quaint city of Detroit.
2. 40 years of inbreeding can produce a being that can survive being rammed into the side of a house with a car, break through walls and survive a 30 plus foot fall onto the concrete.
3. If you want to give someone a warning, just run towards them yelling with your hands flailing in the air.
4. No matter if you're battered looking and hysterical and said you where just attacked and held hostage by a crazed person, the first most important protocols with the police is to have your ID handy and not touch their vehicle.
