Why does it matter what genre anything is?
Hopefully this doesn't take things off topic too far.
IMO it doesn't - a 'good read' is a 'good read'.
However there are those who need to pigeonhole and characterise writing - Publishers, readers, writers, looking for a point of common reference to simply describe their work.
It is sometimes easier to use such terms as areas of common meaning, but there are times when the genre terminology is used against the 'stuff' that we like round here.
There was quite a debate over the terms Sf/Fantasy/Horror/ Speculative fiction a while back at the Forum. Look it up in the Archives or do a search if you're interested. What most people found (if I remember right) was that they were simple terms used because most people knew what was generally meant by them.
Some writers go to great pains to ensure that their work is not labelled as 'XX', not because they disagree with the label or the genrealisation of work, but because those who read such work are a bunch of weirdos who do not deserve to be associated with their writing. Not only that, but saying that a piece of work is 'XX' limits sales.
Then there are those pieces of work that are written, not because the writer has something particular to say, but because it fits the formula, and that the writer can become 'famous' or 'rich' out of writing about it.
Publishers are also often guilty of this one...
I need another book like XX.... which ends up copying cliches without understanding or saying anything new. (A copy of a copy of Tolkien for example). Instead of bringing a fresh view a new style a different perspective, instead each time the style, the view, the vision, if you like, is diluted and possibly damaged, giving those who wish to deride 'better' work plenty of ammunition to use. This is what Voland was getting at, I think!
Minor point, but one which has sadly come up before.
