I like pie previews. These are often far more useful to me as an immediate indicator of appropriateness for my gaming needs.
However, there are a few reviewers I usually take the time to read. They tend to have vaguely similar tastes, or at least they draw the line at vaguely similar points on various issues.
Problem I find is, most often it's not a playtest review, and so (might be) less use than even a mediocre computer game review, for example. That, and there are too few of them, generally. For a given product, I mean. Well, except the occasional massively popular release. But not always, even then.
