i never cared for part 4 they keep meeting people who are trying to murder them and then easily forgive them because they failed at it the actual villain of the season is about as bad as the hair girl who kidnapped a boy and tried to murder him when he turned out to not be the perfect boyfriend she pictured. the difference between him and her is she failed at murdering someone and he succeeded there fore she is a good person and deserves a happy ending and he is a bad guy O_o
basically its a cast full of sociopaths and i couldnt get invested in what happened to them.
