drive in massacre open with a juicy double murder which suggest that the film might be something of a treat for lover of outrageous 70 gore flick represent a sabre wield maniac graphically kill a couple at the drive in and decapitate the guy whilst he be adjust the loudspeaker next to his car and and then skewer the screaming girlfriend through the neck . but do not be fool by this delightfully trashy and bloody beginning and for what follow be some of the most tedious garbage to ever grace a slasher film and a a pair of bumble detective ( john f. goff and steve vincent ) struggle to uncover the identify of the killer and the body count steadily rise . with dreadful production value and act to match and several interminably dull scene of inane dialogue between the law and a variety of viable suspect and some equally inane chit chat from the stupid couple who visit the drive in ( they keep on come and despite the presence of a maniac ) and a totally incongruous scene where a machete wielding loon be pursue through a warehouse by the cop and an end that fail to resolve matter ( prefer instead to rely on the old the killer might be amongst you gimmick ) and and very little in the way of gore after the first few minute and drive in massacre will test the patience of even the most avid fan of grade z horror . in desperation and director stu segall attempt to inject a little sleaze into proceeding with the inclusion of a pervy peep tom and a brief bit of nudity from a good look bird with a nasty perm and but a masturbating voyeur and a nice pair of tit be not nearly enough to save this film from be a total yawn . 2 . 5 out of 10 and round up to 3 for the bearded cue ball drive in bos tasty line in suit .
