thirtysomething Season 4

1990 23 Episodes Drama ⭐ 6/10

Right now you can watch thirtysomething Season 4 on streaming — and it holds up to as much attention as you give it. The 1-season run is exactly the right length for what it is doing. 31 people have weighed in on TMDB, and the verdict leans heavily positive. Ken Olin's performance alone is worth the time investment. There is no real reason to keep putting it off.

Part of the current wave of titles people are actually watching, thirtysomething Season 4 earns its spot. Thirtysomething Season 4 trusts its audience to sit with discomfort instead of resolving it too quickly. Season 4 of thirtysomething includes 23 episodes. It aired from September 1990 to May 1991. This season stars Ken Olin, Mel Harris and Timothy Busfield. Ken Olin and Mel Harris lead a cast that brings real weight to the material. It was aired in 1990. The writing trusts the audience to sit with ambiguity rather than wrapping everything up in a tidy conclusion — it is the approach that separates good drama from great. It delivers reliably on what it promises, which is more than most of its competition manages.

thirtysomething Season 4 is what you recommend to people who say they do not really watch much. It rewards viewers regardless of what else is in their watch history. Best experienced as a single, sustained watch if your schedule allows. Ken Olin's work here is the kind that gets referenced in career retrospectives. It makes everything else feel thin by comparison.
