Absolutely awlful film in the series which is surprising as it's directed by John boorman of Excalibur fame and stars the great Richard Burton who surely did this purely for the money. Where to start..attrocious score, cheesy,reminds me of 70s porn, Linda Blair overacts her sweet socks off if you can call it acting.Burton goes through the motions with dollar signs in his eyes, terrible effects, terrible story, rubbish ending. Probably one of the worse films I have seen. Thankfully the exorcist 3 directed by blatty and starring George C. Scott redeems itself with one of the most chilling moments in horror, I won't spoil it but it's a far superior film, in my opinion it has more chills than the original . My advice give the heretic a miss.
