Since any title containing Roman numerals invites comparison, the answer is: No, Exorcist II is not as good as The Exorcist. It isn’t even close. Gone now is the simple clash between Good and Evil, replaced by some goofy transcendental spiritualism.
Linda Blair is back as Regan, four years older and still suffering the residual effects of her demonic possession. For the most part, however, she’s cheerful and good, seemingly no more bothered by her lingering devil than a chronic zit that keeps popping out on prom night.
She is under the kindly care of psychiatrist Louise Fletcher and Kitty Winn, mom’s secretary from the old days. Another self-doubting priest (Richard Burton) is assigned to investigate the death of the old exorcist (Max von Sydow).
