IMHO "downpour" is overstating things. Right now there are only five reviews: One five stars, one four stars, two three stars and one two stars. That's a fairly even distribution and too early to call out a trend in terms of sample size.
Add to that the two star review frankly makes my brow go Klingon ("it's an election year, you should only publish escapism, not politics" - what's next, "I hate that I have to get up early in the morning, did the book have to involve time travel?" on the next DTI?).
LOL, very true. I don't agree with people who grip simply because it's too realistic or when the author puts his beliefs in the novel.
