I absolutely loved the Last Dance but I really like basketball. I wouldn’t recommend it to non-fans of basketball though (basing this off a small sample size of friends).
FWIW, I was absolutely captivated for all of Last Dance, and I don't watch basketball. But I do have an affinity for "30 for 30"-style docs on the human interest side of sports.
I’m not into sports and I don’t follow basketball. I couldn’t tell you beyond really famous basketball players who the majority of players are. And although I grew up in Jordan’s era of basketball, I didn’t watch his games. All that to say, I enjoyed it.
If you like something, recommending it is fine. Let the people decide if it’s a topic they’re interested in it or not.
