The one hundred third TV show: #816 Modern Family
We originally gave up Modern Family about six seasons in. We started off loving it, but that wear off. I'm not quite sure when it changed, but it started to grow stale. While a gay couple felt progressive when it started, how chaste it stayed, and how much it fell into stereotypes, made it feel stuck in time. There's not always a lot of growth - there's progress in the characters' place in life, but not really in personalities. It makes the entire show feel quite samey and really reliant on the episode and the characters who get focus. Nolan Gould, for example, really grew into his role and is often the best part and most of the kids work better as the series develops. It's clear they can carry more material, but it takes too long for that to come out.
Another show, The Middle, debuted at the same time, airing an hour earlier, and while its start wasn't as strong, it developed into a stronger show. There's a smaller cast, but with a stronger throughline, and they shifted focus throughout. They got stuck too, but there's something more human and more believable to that show than Modern Family is. The humanity can be missing sometimes and there's almost a manufactured cynicism to the formula that means the show doesn't always land well.
