Corrected entry: When Fool first goes into the basement and pulls the TV back to hold up the lighter to the slats, you can see mesh over the wood. Yet minutes later, Fool sees one of the people under the stairs reaching through the slats to pull the TV back into position and there is no mesh.

Corrected entry: Roach sets off a trap which sends "Prince" sliding through a giant slide to the kitchen. That is almost impossible for Roach to build a perfect slide through the house into a drawer in the kitchen - wouldn't the parents notice it?
Corrected entry: At almost the very end, when the people under the stairs are finally outside of the basement and begin coming out of the woodwork (literally), there is one man that breaks out of the wall near the floor to try and grab at the wife. In very plain view, the 'V' slit in the back of his mask is visible. Seems the costume poeple hadn't seen the need to tuck it under the shirt or close it up.
