Glee's Tipping Point?

Full disclosure: I do not watch Glee and do not intend to, so I can't fairly speak to the show's quality, but that's not my concern. From my understanding, a pop culture tipping point usually refers to a product, business, etc. that, seemingly overnight, goes from unknown to wildly popular. I realize Glee has already passed that point but I'm wondering when it will go back?

This show is everywhere and considering I don't even tune in, I know far too much about it. As a casual observer, it doesn't seem very special to have a celebrity guest star or themed episode anymore. We get it, Glee, you harmonize everything from Britney Spears to Journey, so unless you're taking on Lil Wayne's 6 Foot 7 Foot, I really don't want to hear about it. And Ryan Murphy, stop crying about Kings of Leon's disinterest, you seem generally ungrateful. I also never need to hear about this 'racy' GQ Magazine cover ever again. Am I the only one that's had enough?!

Starting today, I'm counting down to the show's demise. Glee, talk to the hand!
