The entire review system boosted by a XP gain system is just plain wrong.
99.99% of the reviews are complete and utter garbage XP farm and makes it close to if not impossible on some novels to actually see if its any good or not.
Not to mention the TRUE rating of the novel is never shown since pretty much everyone rates it 5 stars.
You could write a novel about killing kittens and puppies, but have something else in the description and it would get a perfect score >.>.
At least you added so you can see if someone read any chapters, but would be a better if the entire xp system went away from reviews. Or put something in place so people who just write reviews for XP (0-5 read chapter derps) gets automatically filtered and hidden and wont affect the score, but they still get their shiny XP.
And if they actually pick up the novel they can get a popup after 20+ chapters to rewrite their review.
