Each category is really open to interpretation by the reviewer. We have no idea what they might write, but rest assured... we aren't trying to create a space for a standard style of review, although we might include these on occasion.
Instead, we want to send out reviews on any kind of thing, with an angle that's anecdotal, funny, challenging, critical, or really whatever the review(er) calls for. We want you to laugh, to cry, to think, and hopefully occasionally question your worldview.
