I can't understand all of these negative reviews. What were these reviewers smoking? This is a wonderful film, in no small part thanks to William Peter Blatty's funny script. And the scenes with Bob Cummings doing the child psychology bit are cute. There's something about Blatty's sly, corny humor that always gets to me. If you haven't read his memoirs, I highly recommend them. But yes, I wholeheartedly agree with the reviewer who tried to counteract these absurd negative reviews. This flick is a keeper.
