Well this is a weird one. Interesting but weird. A mix of a Gidget type of teenage comedy with a spy spoof. Not sure why it's so hated. Leonard Maltin gave it a BOMB rating, for crying out loud. That's completely unfair. It's a cute and harmless little bit of fluff with some funny moments, especially early on. I liked Kathy Dunn and Lynne Sue Moon. Maybe people hate it because it's from William Castle and has a misleading title that makes it sound like a horror movie? I don't know. Admittedly the fun and cuteness of it wears off after awhile. When it seems to take its spy plot seriously is when things get a little dull. But it picks back up towards the end. I didn't think it was bad at all. Ignore the overly harsh criticisms and judge it for yourself.
