Every single tag, category, year, month, and day has its own archive page in WordPress. So you could use the category reviews, and then just link to that category.

As you can see, Graphene makes use of Category descriptions (a much underused feature by most WordPress users, if you ask me), so it can almost be like a “sub-blog” within your blog if you link to it.
