Killers in the house is an excellent suspense seen the limits of a made for TV movie. It isn't violent or hard to understand.
The film is without a doubt inspired by The People Under the Stairs, de Wes Craven. The house has gadgets and hiding places, but while staying realistic. The performance by Andrew Divoff isn't as impressive as in Wishmaster but is still excellent.
I surprised myself tightening my fists many times during this movie and really got caught up by the suspense, while still trying to forget the low quality of images. I recommend this movie under the condition that you are warned that it is a thriller and not a horror movie.
