This mind boggling, utterly strange sequel to the classic 1973 original is certifiably bad, although certainly not the worst movie ever made.
Linda Blair returns as Regan, now under the care of a psychiatrist (a deadpan beyond belief Fletcher).
A priest named Philip Lamont (Richard Burton) is assigned the task of investigating the death of Father Merrin which occurred during Regan's exorcism.
We get the unnecessary revelation that the girl was actually possessed by an African demon named Pazuzu. (And here all these years, we just thought it was the regular old Devil!)
Meanwhile, turns out Regan is a rare sort of telepath with repressed psychic abilities. As she and Lamont follow the path of Pazuzu, they use her gifts to alternately repel the demon and uncover the truth behind its malevolent evil.
Ellen Burstyn is sorely missed here, her character of Chris MacNeil being away on "a film shoot."
And in one of the more depressing developments, Sharon Spencer (the secretary played so winningly by Kitty Winn in the first one) is annoying to the point of making one indifferent to her violent demise.
Perhaps the only redeeming factor here is the performance of the lovely Blair.
P.S. to director Boorman: Enough with the locusts...
