There are two very different versions of this: Lisa and the Devil is the one to watch, House of Exorcism is a butchered version with about a third of the film cut out and embarrassingly bad exorcism scenes inserted.

Out of Black Sunday, Kill Baby Kill, and Blood and Black Lace, I enjoyed this one the most. I found very interesting and it kept me constantly curious where it was going. I don't know why some people found this boring, I didn't find boring one bit. I tried watching house of exorcism to see the difference and couldn't get through it.

Geez Louise! This one is a real stinker.
