The main problem with this Fulci entry isn't entirely unexpected, being the somewhat incoherent plot the film sometimes pushes. The gore is, of course, fantastic (the bat attack, in particular, was cheesy fun), but I couldn't get over some of the unexplained subplots, and that brought the film down a bit for me.
What do you think about this Fulci entry to the genre?
