It doesn't prejudice me against the next book I read from the same company. There are strong comparisons to how media celebrities view publicity. They don't really care if it's good or bad as long as they're noticed. Believe it or not, even a bad review sells a product. There's always a percentage of the readers who don't believe the reviewer and will check it out for themselves.
Criticism tends to be a personal thing at the best of times.
It would be impossible to account for all tastes although I do endeavour to indicate who particular books might appeal to. Things like this can't really be put in an article but need to be said occasionally. If anything, this is a carry-on from last month's editorial. If SF is to be read then it has to have a percentage of promotion. We're in there swinging for you.
