I felt it lacked only a few things. Personally I think if there was just a small improvement in the following, this could of been a great movie; - screenplay - direction - actors - cinematography - sound - lighting - production - make up - costume - catering. However with that said, it's does miss the mark considerably in most areas. I was caught a few times watching my toenail grow rather than focus on the masterful delivery of this most awesome story. Even though at times while watching this movie i thought it couldn't get any worse, the marvel that was this screenplay takes the viewer into a new, highly nauseous, direction. If the choices where to insert a part of your body into a closed box and inside that said closed box was a half starved rat OR to sit and watch the magic that is "Home Invasion", the ravenous rodent option would certainly need some further consideration.
