Tonight I watched Deadly Friend, A Wes Craven directed film from 1986.
A teen genius named Paul moves to a new town with his mom, and his home made robot, BB. He becomes friends with Sam, the girl who lives next door to him. When BB is destroyed by an angry neighbor, and Sam is accidentally killed by her abusive father, Paul decides to bring Sam back to life by putting BB's brain chip into Sam's head. It works. Sam comes back as a human with a robot brain, and she's also murderous for some reason.
Lordy, this is one of the fucking stupidest movies I've seen in a while. The entire thing was just absolutely ludicrous. yet the movie seems to be playing it totally straight.
I gotta say though, I kinda enjoyed it. It's bad in the best kind of 80's way.
BB the robot is like Johnny 5 with down syndrome. He's right up there with Paulie's robot from Rocky 4 as one of the dumbest 80's robots. He makes these unexplained gremlins noises, and it's just hilarious. BB is voiced by Charles Fleischer, who did the voice of Roger Rabbit.
Kristy Swanson's performance as a killer robot/human hybrid is good. Most of the time she just kinda has a blank stare.
The greatest scene in the movie is when Mama Fratelli is killed. It's too awesome to describe, so watch for yourself.
