Representing the (somewhat fatigued) tail-end of the "Beach Party" saga, minus Frankie and Annette, this haunted house comedy has some style in the live-action cartoon vein, but is hurt overall by an unenthusiastic cast and too much chatter. Sleepy Tommy Kirk and distracted Deborah Walley are involved in the reading of a will in a spooky mansion; Susan Hart is a sexy apparition (wearing a dopey-looking blonde wig for F/X purposes); Boris Karloff saunters through, tossing off droll comic lines in a debonair manner; Harvey Lembeck returns as Eric Von Zipper (although he doesn't look happy about it); and Nancy Sinatra is one of the teens there for a slumber party (she sings "Geronimo" poolside in the film's best sequence). Not terribly witty or lively; most of the kids on display are artificially frantic and 'nutty', waving their arms about. The movie desperately needs more music and more special effects. It relies too much on the talk-heavy plot, which is its weakest link. ** from ****
