I remember when this show had 7.1... What happened?!

Sure, that grade as well is not the best either, when it's at least 7.0, you know a show gets a moderate amount of respect. But now this just has 6.8. It's a terrible grade in tv-series standards. In fact, a bunch of my favorite shows is getting a lower grade! (Aqua Teen Hunger Force, Robot Chicken, to a lesser extent Family Guy)
