My SO and I binged this show over the last few weeks. We both really, really, really enjoy it, and have also adopted some of the phrases into our everyday life (sneak attack, okay see you). I like all of the characters, and I laugh out loud A LOT with this show. It's a good mix of dramatic beats, comedy, and good fun.
And then season 4 happened. It was okay, but not as great as the other seasons. It had some gems, for sure. Near the middle or so (it's hard to keep track during a binge), I laughed less and was annoyed more. To me, it seemed like many of the characters were dumbed down or exaggerated to force "funny" plots, and it started to remind me a little tiny bit of the Goldberg's (I'm so, so sorry). I also found myself yelling "JUST BE DIRECT AND SAY WHAT YOU MEAN" a lot; in the earlier seasons, it was refreshing when characters were direct and said what they meant. The storylines were better for it.
The worst decline is Pastor Nina, though. She started out highly competent but funny, and now she's unethical, incompetent, and character assassinated. It's not funny how many times she's completely breached client confidentiality, with regard to marriage counseling and individual counseling. When she "sneak attacked" the Kims into group marriage counseling, I could've reached through the screen and shook her (INFORMED CONSENT!). Then she was portrayed as being entirely unprepared and unskilled at running the counseling group. Oh, and then she started dating a client, apparently in the middle of counseling said client, which is pretty much #2 on the DON'T DO THAT list. She partially represents my profession (...I'm not a pastor), and I can't with her. I want her gone, and I loved her when she first arrived.
I hope season 5 is more like seasons 1-3. Every show has a slump, and season 4 was a slump for me. Still glad we found it on Netflix and gave it a go, and I'm looking forward to new episodes. (A roommate shake up could be a good thing; wouldn't mind Jung, Janet, and Gerald living together, with Chelsea long, long gone...)
