Bests & Worsts Reviews from Amazon

Any Sf author who believes there is a dark side of the moon, should be writing in another venue. As readers of these reviews know, the moon has a back side due to tidal lock, which has same day night cycle as front side. Thats why there isnt always a full moon. The only difference is that on back side, earth never rises above horizon. How can one take such a SF author seriously?
