The problem with The Class is that it has too many characters without enough intersections. Friends worked following separate storylines by having the characters intersect at a certain point in the storyline. That seems to not happen as much on this show. It leads to enjoying some plotlines but being able to zone out for others--such as any plotline with Holly. (The one note joke about her husband possibly being gay and she not knowing is wearing very, very thin).
But this week's story pushed Holly to the side and instead concentrates on just two plotlines. The problem is that we're covering the same ground Friends and Seinfeld did, only they did it better. The show is working so hard to keep the Kat/Ehtan thing on the backburner that Ethan's pretending to be another guy to impress Sue is...well, you can just see its doomed from the start.
