I remember this being pretty crappy. But I had to buy the dvd anyway, just for the Richard Johnson interview. :) And its a good one too!
I've never watched BEYOND THE DOOR but I quite like the EXORCIST rip-offs I've seen so far so needless to say I have to check this one out as well. I thought LA OSSESSA was great! Besides, taste is a acquired taste and there are members at Dvdmaniacs who claim this is the best of the rip-offs there is. One member even prefers this one OVER the original film!
