"Karlaboasts incredibly impressive performances from the  leads, and Laura Prepon does a stand-up job as the eponymous character,  effectively casting aside her70s Showpersona more than any of the  other sitcom cast members have managed over the years since the show's  cancellation.Prepon manages to stay stellar throughout the film, giving a very  restrained, natural performance as a woman who would do anything for her  man.Actor Misha Collins is equally brilliant as Paul Bernardo. He embodies the  bi-polar aspect of Bernardo's character so believably as to be frightening.  Bernardo's transformation from sex fetishist to wife beater to rapist  happens gradually and naturally, up to a point where he stops being a  sexually frustrated filmmaker and becomes pure evil. All of which seems  incredibly accurate, thanks entirely to Collins' performance." --BeyondHollywood.com"That '70s Showstar Laura Prepon is downright chilling in  her portrayal of Karla Homolka. This movie is profound on many levels and  its jarring look at anti-social behavior is right up there withHenry:  Portrait of a Serial Killer,KidsandKen Park." --phillyburbs.com"Beware a film that will keep you up at night." --DIGITALJOURNAL.COM"Disturbing, yet compelling...downright chilling" --MCG's movie picks"Prepon and Collins,  bear a chilling resemblance to the couple  once dubbedThe Ken and Barbie killers." --The Globe
