It's going to be growing pains for the new few seasons. Its on very shaky ground not knowing if it can sustain itself without the original cast bopping around. The real issue I'm having is that every point in this season I've been really embracing the new cast members and starting to give a fuck about them they do some nonsense bullshit with Finn and Santana and Rachel and Kurt that reminds me that it 'isnt the same'. Which again, isn't a bad thing. But they need to commit to that. Instead of trying to keep the guys that are ONLY sticking around for the original cast strung along for as long as possible with 6 minutes of NYC storyline each week.
These are supposed to be kids in highschool, I'm glad each of them has a shelf life of 4 years, and they knew this when they started it...ahem. Sorry. I'm done thread hijacking. :-P
