Abby has been called allot of things, most prominently a rip off of the Exorcist. That's not really fair as this is actually a good film, where as the Exorcist sucks. Abby is about a counselor, named Abby who get possessed by a crossroads demon her father freed while on an exhibition
She becomes evil and horny as its a sexual demon. So her dad has to come home and perform an exorcism. This is a good Blaxploitation film, and just a fun film in general. Like I said I don't like to compare it to the Exorcist because I like this one.
