I am a HUGE fan of Horror, Suspense, and Thriller movies, however I have often wondered about the intelligence of the characters.
Such as asking these questions....
Why would you go up the stairs, instead of getting the fuck out of the house?
Are you seriously going to open that door?
What the hell are you doing?

This video clip is a trailer based just on common sense...
Hold on to your seats...
You're in for one heck of a ride...lol
