Reviews done after you've used the book in play.
I disagree for a couple of reasons.
First, as Crothian said, it's not always feasible to play it. And even playing it, it sometimes takes several times playing it to find something that doesn't work as well.
Second, though, is for me that's not as important as how much the book inspired. I rarely use a book verbatim, usually tailoring things to fit my campaigns. So for me, it's more about how inspiring the book was even if some of the book wasn't the best, it still gave great ideas.
That's just me.
