Kim Newman from Empire Magazine awarded the film 3 out of 3 stars, writing, "Derivative of everything from "Duel" to "Jeepers Creepers", this is good, trashy horror fun with a streak of Jackass-style grossness, some leftfield surprises and the always-reliable sense that the middle of America is a sucking pit of desperation that's out to get you." "Arrow in the Head" rated the film a score of 7/10, commending the film's cinematography, slick direction, and humor. The site concluded their review by writing, "With its strong dose of 'out of line' comedy, sometimes at the genre’s expense, and its extreme display of gory goods, "Monster Man" had me having a blast in my seat most of the time."
