This brisk little thriller is a textbook example of a giallo: Perche Quelle Strane Gocce Di Sangue Sul Corpo Di Jennifer? doesn't make a lot of sense but it keeps the viewer guessing throughout and packs plenty of wild visual excess into its running time. Ernesto Gastaldi's script is thin on characterization and logic but delivers all the elaborate murder setpieces, red herrings and radical plot twists the genre requires. Director Giuliano Carnimeo avoids allowing the viewer to dwell on the gimmicky nature of the storytelling by maintaining a snappy pace and trotting out a vast array of eye-catching visual devices (zooms, fish-eye lens shots, point-of-view camerawork) to keep the viewer's eye dazzled throughout. The performances are limited by the weak characterizations but Edwige Fenech is easy on the eyes as the film's heroine and George Hilton makes a decent square-jawed hero. All these elements make Perche Quelle Strane Gocce Di Sangue Sul Corpo Di Jennifer? a fast-paced, occasionally startling piece of macabre eye candy. Viewers looking for narrative depth won't find much of interest here but fans of 1970's Eurotrash are likely to consider it a kitschy delight.
