The Eerie Midnight Horror Show or Paul Nashy's Exorcismo, Lisa And The Devil isn't an Exorcist rip at all.
Mario Bava does what he does best and directs another atmospheric Giallo.
Lisa is played by Elke Sommer who I remember best from another Mario Bava collaboration Baron Blood. She is stranded in a spooky old castle where a young man, his blind mother and Telly Savalas reside. Lisa believes Telly Savalas's character to be the devil and this is neither proven nor disproved but there is much worse things to worry about at hand. For one a killer is roaming about the castle killing people in very violent ways. We have stabbings, achy-breaky skulls are caved in with blunt objects (complete with red splatter that splashes all over Bava's camera lense), women are impaled on poles and in one of the most gratuitous moments of violence a man is repeatedly run over by a car. His mangled body is crushed worse and worse with each passing of the vehicle.
This one is bound to bore the average gore hound who is not used to this Italian brand of film making. Check it out if you have an open mind and can appreciate a bit of beauty with your horror.
