I disagree. In my experience, user/customer reviews have been vastly more useful to me for learning about serious safety or quality issues with a product or service than they have been for any purpose (unspecified because I really can't think of any) predicated on learning about specific users' weird gripes. I can practically smell the unreasonableness dripping off that review somebody linked above, and I would ignore it if I spotted it in a list of reviews—but unfortunately I can't ignore it out of the aggregate rating.

Anyway, this isn't going anywhere productive, so I'm out.
