I've just added a very limited feature that has been requested over and over again. If you click on a genre while viewing a series, it will pop open a window with an option to "View other series with this genre". I am writing an expansion to this which will allow you to search by genre selection in the future--but for now this will have to work.
I spiffed up the reviews section a little bit. The reviews now have an overall rating (which is the combined rating of all 5 sub-ratings) which is displayed by some cool looking stars, and if the series is in our database, an image is now shown next to the review. Just a little heads up! More cool stuff to come!
