this be one of the most amateurish film i have ever see . while film like plan 9 from out space and swamp woman and they save hitler brain be all notoriously bad film and i really think these movie and one like it seem so polished and well make compare to drive in massacre . tor johnson and criswell be much good actor than the folk in this turkey . yes and folk and it that bad . the film begin with a couple be kill by a sword wield murderer at a local drive in theater . it pretty funny watch the guy get his head chop off and a the plastic head will make you chuckle . logic isn not a problem in this film and a they just do not bother with any at all . think about it . three night in a row people be butcher at the drive in and yet they keep the place open and people continue to fill the place every night . then and when the two least likely look detective get involve and you laugh even louder . that because it seem a if there be no police force just these two fat guy that look like brother . you do not see a police station and other police or even a police car just an old wreck of a car that barely run . talk about low budget . while these two guy be obviously not professional actor and they be good than most folk in the film . a for the manager of the drive in and he hilarious and a he be a completely one note actor . all he seem to be able to do be scream and curse . and a for the rest and the loser who live at the theater and the pervert who like to watch couple make out and etc . and a group from a small town amateur theater group could have easily handle the act much well . it obvious that the film maker want to put anything on the screen and have no illusion about the quality of the picture . so why if this movie be so inept and so cheap and so stupid do i even give it a 2 and not a 1. well and there be two thing i do like . first and the scene of the cop undercover at the movie theater be awfully funny . second and while the end be steal from william castle film the tingler and it still be a good end for this exploitation film and end this dreck on a positive note . fyi there be a small amount of nudity and lot of curse in this film . parent should be aware of this before allow the munchkins to watch drive in massacre though with a title like this and i guess you aren not expect a disney film .
