Weird! This is one of the most bizarre horror flicks I've ever seen. But weird can be good, and in this case, it's definitely good! The beautiful and sexy Sondra Locke is at her very best as the tormented teen. Mary Ure and Signe Hasso are appropriately sinister as Locke's overprotective mother and grandmother. Robert Shaw is the disturbed young girl's estranged father who returns home to announce he's going to marry lovely Sally Kellerman. Naturally, several strange and dastardly deeds occur before this event can take place. The film is by all means an effective suspense story(all right, so it borrowed here and there from PSYCHO), but does have its shortcomings. The movie was very severely cut to avoid an R rating and slide by with a PG. Bad editing makes it all too obvious where the missing footage should be. But, it's still a worthwhile thriller with genuine scares and great acting.
