I just watched the Prowler. From the get go I noticed the heroine looked a lot like Amy Steel. But I got a big deja vu feeling during the final scene. When she is going up against the killer, and he uses a pitchfork, and even stabs it through the door, while we see the look of horror on the girl's face. That reminded me of F13 part 2 as well. And then...she hides under a bed, while the killer is looking around the room for her. While she is under there, a rat appears, almost making her squeal. That was almost exactly like part 2 as well. Nothing too major, but worth a mention I think.
