Rotten Tomatoes, the film holds an approval rating of based on reviews, with an average rating of . The site's consensus reads, "Over the top and enthusiastically strange,
PG: Psycho Goreman delivers all the cheesy midnight-movie goodness promised by its title." Barry Hertz of
The Globe and Mail praised the film, writing that "if you happen to be operating on Kostanski's very particular and peculiar wavelength, the movie is an absolute riot. Working with few resources, the director creates a wildly colourful, surprisingly epic universe full of alien landscapes, energetic set-pieces and a fantastical creature design that strikes just the right balance between inventive and derivative."
Owen Gleiberman, in his review of the film for
Variety, concluded that "As satire,
Psycho Goreman is no
Planet Terror, but it's a droll enough schlock-in-quote-marks diversion, and part of its appeal is just how damn cheap it is. In the omni-tech era, it's fun to see a filmmaker build an FX fantasy out of scraps, from the ground up."
Bloody Disgusting's Meagan Navarro wrote that "We may not care about the human protagonists by the time the end credits roll and the '90s-style end credit rap kicks in, but [
Psycho Goreman] does leave you hoping to see more of P.G. and his continued quest for domination of the cosmos." Richard Whittaker of
The Austin Chronicle gave the film a score of three out of five stars, writing that it "channels Saturday mornings loaded with
Power Rangers reruns, just with the added realization that the creatures were supercool." Chris Aitkens of Nightmare on Film Street praised the film, saying it was " a vehicle for over-the-top violence". Mary Beth McAndrews of
Paste called the film "a necessary explosion of ridiculous fun in a time when it's needed most. [...] The extreme tonal shifts from hard sci-fi to family comedy will be weird for some, but Kostanski never hides what this film is: Ridiculous." Conversely, Simon Abrams of
RogerEbert.com gave the film one-and-a-half stars out of four, writing that it "isn't clever or lively enough to be more than fitfully fun, especially given how much time is spent mocking generic, but painstakingly recreated plot contrivances."
Slant Magazines Pat Brown gave it two out of four stars, calling it a "tongue-in-cheek gorefest" but also "a somewhat empty film."
