When I read a romance, I expect to find a plot. The main plot may be the relationship, or the relationship and the external plot may be equally important, but either way, it has to be there. "How are we gonna fuck?" is not plot. It may be PWP, but that's not what I was promised by the blurb.
When I read, I expect to find dialog that sounds like people might actually speak it. Yes, dialog in stories can't sound exactly like a conversation, you have to take out the ums, the pauses, the digressions into how the garden's looking and will there be rain, but it has to sound like real people are involved. If Siri can manage a better conversation, there's trouble. If the dialog sounds like a particularly dry textbook, there's real trouble.
When I read, I don't want to be intruded on by the author's life. I want to be in the story, I don't want to find myself thinking, oh, look, this must be a rewritten part when she switched publishers, it's so much better. I don't want to think, oops, must have been in a hurry to finish, she just wrapped 5 plot points in 3 paragraphs. I don't want to think about the author at all. I want to be engrossed in the story.
I've read some great things lately and I've read some disappointing things lately, not all of which got reviewed. The contrast is making my head hurt. That is all.
