SBTB *is* an extremely reputable, professional-level review site. Not only that, they have a keen understanding of their readership. They are very open when they (rarely) don't finish a book. They lay out all the reasons, which they did here, in detail. This statement is made within the first 50 words of the review (I know this was mentioned before, but I want to quote it):
First, a few points.
I am aware (and was aware when I started this book) that this is Not a Romance. I am not carrying into this review my romance-reader expectations on happy or optimistic endings.

Romance readers don't
only read romance. We are prolific readers, and often expand outward to other genres. If there is a book that is being marketed with romantic elements, it's probably a bigger draw for many of us. So I think it's entirely fair that SBTB warned their readers about a MMC who has extramarital sex, on the chance that they might expect something else, and that he really does some stuff that typical romance readers find off-putting. There are problematic elements of this book that they know their particular audience wouldn't like, and they, with full disclosure, posted a review. Whether or not to read the book, of course, is up to any individual reader. I loved the Sookie Stackhouse novels, but I can see how a review like this could be published.
As for Romance v. romantic, the Sookie novels are a pretty good case. Definitely not big R-romance, but a heckuva lot of romance readers I know have an opinion on Bill vs. Eric vs. Alcide vs. Sam and Sookie. There is plenty of crossover with romantic + X-genre. I don't think that's problematic. It's when big-R Roman(ce) is used that it gets sticky. When I read the words "romantic elements" I don't equate that with Romance (meeting the RWA definition) at all, but then, I'm only one reader, and one who's been indoctrinated with the terminology.
