Spoiler alert ahead.
"The creators of the film initially had an even darker ending in mind. Rocky (Jane Levy) was not supposed to make it out of the house. Instead, the Blind Man (Stephen Lang) locks her up in a cell, and even though the police come to investigate the burglary, they miss the door to her cell. The writers thought that this ending was too downbeat, so they changed it to Rocky escaping, but the Blind Man getting away with his crimes." Oh man we were so close to a happy ending. Damn it. This ending gets this movie 8 out of 10 from me but unfortunately it's a 5.
