i don't think reviewing literature, especially erotic literature, is an exact science. If the story is 'technically' good, then say so, if it has a few errors but really does it for you in the way the kink has been written, then say that also, if it is written fine but just isn't your 'thing' then there are ways of saying that without saying 'the story was crap' just because it didn't get you off!
