A score of one out of five was awarded by Vegan Voorhees, which described the film as "idiotic" and concluded the review with, "Despite director/writer/producer/actor Lindbergh's impressive enough camera work and production Polish, everything that happens in Bunnyman happens wrong. Like a bitter, out of date Easter egg, it's shiny and pretty on the outside and sickening under the foil". 28 Days Later Analysis called Bunnyman an incompetent and frustrating mess, gave it a "generous" three out of ten, and wrote "atrocious acting, zero character development, no tension, zero sense of pacing, poorly written, continuity errors abound, audio problems, ADR and dubbing, poorly written characters, forced tension, meandering story, etc." Gorepress also gave an overwhelmingly negative critique, stating "The Bunnyman Massacre is literally the worst film I've seen in years. Decades, even. Why? Well – simply put – because it's appallingly made on every single level".
