Fulci playing himself, and some ruddy great gore scenes. Who cares if the rest is a load of twonk.
I'd braced myself for the worst before watching this, so was pleasantly surprised when it wasn't as atrocious as I'd feared. Far from Argento's best work, and as others have said it does feel more like a TV show than a movie. Adjust your expectations accordingly and it might not be so bad an experience.
