Werewolves Within is more playfully thrilling than scary in tone" and that the screenwriter "fashions all her characters with memorable attributes and plenty of social observations, yielding a compelling range of suspects none of which you can write off entirely.

"[23] Jennifer Ouellette of Ars Technica wrote, "Werewolves Within is first and foremost a successful comedy, and the ridiculously talented cast members all possess the skills and onscreen ensemble chemistry to make the script come alive.

"[25] Noel Murray of the Los Angeles Times called it "[b]oth funny and snappy," and that its "catchy concept is made even more entertaining by a cast of accomplished comic actors."
