These episodes have all been very bland. Basically every episode starts out with some random event, Will gives the students some random assignment, and then the rest of the episode has the students following some sort of theme and singing about random stuff related to the assignment. Then the episode ends with them all coming together and learning something.
There have been barely any good songs, and I feel like there hasn't been any build up to regionals. The episode before sectionals had a feeling of excitement to it. Sectionals was, in my opinion, the best episode of the series so far. I'm hoping regionals will be as good, but it just seems like there are 30 random plots that may-or-may-not be-resolved-but-I-don't-know-whatever.
Plus, recently the characters have been so unrealistic! Artie has basically become "the kid in the wheelchair" who never gets any plots or has any personality except for his being in a wheelchair, Jesse apparently hates Rachel and the Glee club for no reason (last episode he was confessing how much he liked her?), and there really wasn't a logical reason for why Rachel and her mom didn't want to see each other anymore.
I have no idea what songs they are gonna do on the finale, but I hope it can make up for some of the crap recently.
