Maybe this clip isn't a good cross-section of what the movie is really like, but this doesn't seem particularly funny, cheesy, poorly made, or have exaggerated acting, etc. - all the things funny about "blacksploitation".
This slip seems like it's from a half decent movie. The priest is a good actor and Abby is sufficiently creepy. These 3 stars go to the confusing title making it sound like Abby IS the exorcist.
Seriously though, the original title was supposed to be "The Blackorcist".
Featuring William "Blacula" Marshal as the preacher who's wife is possessed by an African sex demon (the thing looks a bit like the Hulk sculpted out of Play-Doh).
