Something really struck me in this episode. I thought this was perhaps an inverse of The Fluffer, one of my faves, but it didn't work.
First, Jessica and Nick's chemistry is all off. She seemed more maternal than romantic. Second, in The Fluffer the story got a chance to develop. Here, having to switch stories with Winston/Aly and Schmidt and CC, then jamming in the stuff with Reagan and Jess, there was no real banter time for the nick/jess stuff to be satisfying.
I love the nick/jess combo, but it's hard to create a strong dynamic when you're carrying so many characters. I like Winston and Aly, but they weren't even connected to anything on the story at all. In my opinion, the story flows better when the character stories intertwine somewhere.
For me, seasons 1-3 were great (although Jess and Nick's breakup reasoning was ridiculous). Since then it's been a struggle.
