Okay so this has been driving me crazy lately trying to remember a horror movie I used to watch on tv at my grandmas house back in the early to mid 90's. I will relay to the best of my ability what I remember. The movie was about this girl who was probably 15-20 years old. She had blonde hair and was pretty cute. She turned out to be a robot underneath her skin. She went around this neighborhood killing people. One scene in particular that I remember was of her killing this old woman in her house with a basketball or something to that effect. I think there was a little boy who knew what was going on/had befriended her. She was pretty evil from what I can remember. Anyone got any ideas?
