The fourth and final Hellraiser film to be shown in theaters, Bloodline looks like it might have sought to be a new trilogy, as it's story is much more ambitious than your usual 90 minute flick. However, if (blog post) they did that, then we'd have to wait quite a while for science fiction movies our Pinhead, and we can't have that. Surely, having Pinhead appear in the first second is far more important than coherent storytelling, or even keeping studio meddling down far enough (blog post) so the director DOESN'T walk off set in anger. Surely.
