You have to accept the critical reviews if they treat you with respect. Actually, it's one person's opinion. So, it's a concern but not an overriding one, and I don't stay up nights worrying about reviews. But there are certain people I respect who I hope will like a book.
You hope that people read your book and say "Yes, this is the way it is or could be." But then you have no way of knowing until the reader reads the book. Actually, the critical response doesn't worry me. I've had very few reviews that have upset me.
