Kitten With A Whip knockoff...
I was just watching Mystery Science Theatre 3000, featuring the movie "kitten with a whip" (ep. #615 i think. Sad to say, Knock Knock is even worse than the movie they were ripping on. Sad how remakes are so often revenue streams as opposed to simply better made, more provoking, etc.
