Playing With Dolls has a really cool looking killer but suffers from its amateurish unknown actors and general low budget feel, despite being shot rather well.
Have you seen this movie?

I quite enjoyed parts 1, 2 and 3 and I hate slashers. Its was very shitty in some ways but not Uwe Boll level shitty. Im hoping more movies will come and they will continue the story of the serial killer and Richard Tysons character.
