It was an alright premiere.
It's difficult to judge, because, while the characters were once again different from where they were last season: Santana flip flopping for the millionth time between cheerios and glee club, Quinn bizarrely shunning her friends, etc. who knows how long any of that will last? With the new writers, one would hope for some continuity, but the show has an abysmal track record in that area, so who knows who it will go? I hope it sticks.
I like the theme of Finn (and possibly others) not knowing what to do after high school. I hope they fully explore that this season, but I expect them to get sidetracked with tater tots or something equally irrelevant. Kurt and Rachel's struggle to leave their hometown for brighter things is well done, and I hope they continue with that as well.
Schue and Emma are terrible, and completely suck the life out of every scene.
Sue is an embarrassing, unfunny cartoon at this point, and nothing she does means anything.
Song selection was hit or miss. I liked Blaine's number and the competitive high school musical bunch, as well as the final performance, but the rest were flat.
