The twenty-eighth TV show: #409 Roseanne
Roseanne has an interesting history. Created in part as a reaction to the upper class nice lives of shows like the Cosby Show, it focuses on a lower class family that constantly has to stretch to make ends meet (something partially abandoned in later seasons, but at least always somewhat of a presence). The leads aren't particularly attractive, and the show relies on the wit involved in the family sparring with each other, combined with touching family moments. The show could work as a dramedy - an average episode feels like it could be a special episode on many other series.
What helps is that the joy of them working together carries over. Despite plenty of issues, the actors get along and are often seen nearly breaking at each other's jabs. It shows they care in a way that comes across on screen. There's an amazing secondary cast - Roseanne Barr is good, but Laurie Metcalf and John Goodman especially lift up the material in a way that is unbelievable. An early episode has some long scenes with just the two of them, and the way they play off each other is both funny and works to make a point.
The show is timeless, in a way, and touches on issues that still affect us now. It was amazing to get back to - far more so than you'd expect from an 80s sitcom, and the way this was presented.
