Review of The Open House

What shit is this. Horrible movie.
SPOILERS:
- what happened to that blocked passage way?
- yes we know his father passed away but how? drunk driver? on purpose? did the mother do it?
- who the shit is the guy killing them?
- why didn't her sister come back to the residence after to grieve?
- the neighbour where the shit are you?
- why didn't he RUN for help?
- why did he KEEP staying in the house???

This was dumb.
