Being a reviewer is not always an easy job. You certainly cannot please everyone. In many ways it is a tightrope act. On the one hand you want to be fair to the artist, but on the other hand writing a rave review for a mediocre product does no one any good. People will go out and buy stuff only to discover that it is not nearly as good as the review would have you believe.
I tend to work on the assumption that the 'thing' being reviewed, and it could be a book, music, or a movie, is the very best that the artist can do, he or she has put their heart and soul into it. On the odd occasion that I come across something that I genuinely do not like, I still try and find some redeeming feature in it.
For the most part this formula works quite well.
But what happens when you write a good review and the artist hates it? Well this was a first for me. I reviewed an indie movie, documentary in fact, by a fairly 'off the wall' film maker, I gave it a pretty positive review, tho I did remark that the film maker seemed a little eccentric. Well the guy went up one side of me and down the other! So F him, and the horse he rode in on!
He will get no further coverage from me. In fact he is such an ass, I won't even share his name.
