I don't usually write reviews on IMDb but felt compelled to, considering that Cleverman really succinctly questions modern Australia's political, social and racial climate. In fact, the nature of other reviews, positive and negative, are actually a testament to how well this series has done in exploring key concepts. Namely, Cleverman is actually serving its purpose very well, considering the number of racist reviews!
Cleverman is telling a story about how Australian's (and perhaps more broadly, general society) are fearful of those that they don't know and minority cultures. In the series, a society is afraid of the insinuation that another culture might be different to theirs and feel the need to put them "back in their box". It is truly poetic how the actions of many of the antagonists in Cleverman, are so well mimicked by the negative reviewers here on IMDb.
Xenophobia is still relevant and Cleverman clearly explores this theme effectively and strikes a chord with a number of viewers.
I would recommend this series for those looking for something different and who are knowledgeable of the science fiction genre (and that speculative fiction sits within it!) It is a really unique show that explores some aspects of Aboriginal folklore from well respected artistic groups. It's also excellent for its consideration of political rhetoric around tolerance; exceptionally relevant viewing.
