Jeremy Milks’s review published on Letterboxd:
In the tiny subgenre of "Hippie Horror", this one stands out for good reason. It's insane. Simple concept executed with complete bad taste and disregard for logic. Very similar vibe and look as an H.G. Lewis production but way more manic and drugged out. Features some of the most wild over-acting you'll ever come across. Simply put, this is a trash masterpiece, from the title on down. There should be way more "humans with rabies" films out there. Stay away from those meat pies.
