It's not so much a killer doll movie as it is marketed to be. There are some giggles to be had throughout if you can appreciate its crude level of humour and some scenes that will make you just wonder, "what the fuck?" but it isn't a scary movie.
Have you seen Triloquist?

This movie really doesn't look like it'd appeal to me, based off both what I already know of it and your review.
I'll try to add a scene from it soon.
Oh, this. I caught it on the Horror Channel once. I don't remember much about it other than the two main characters having a weird incest thing?
Yeah, there is some incest stuff going on between the main characters. I actually got a free copy of this from Dimension Films about 10 years ago when FE had heaps of people on the forum.
