Realism is best portrayed with unrealistic plots. Dont believe me ? Watch this series. It works like a graphic novel would and if it was one it would be praised. You try to imagine Rebecca Hickeys mindset and that should grip your imagination. The acting and credibilty is a mixed bag but as far a tv series go this works fine. The reason is does work is the symbolic levels here. One that tells you that society and family is not your friend unless you are able to befriend it / them. The symbolism is not very abstract Its quite obvious in the admittedly sub par closure plotline. But in portraying alienation and cynicism in rebeccas actions the plot does achieves one thing. : Reflecting that we all get away with 'murder' all the time and it borders evil unless we takes step to counter it.
