Abrupt ending
I am guessing this did not get re-newed based on the epilogue at the end that basically fast forwarded the rest of the story into two short sentences, then told us why it mattered in a nutshell. The wikipedia of mini series.
Why end the show finale on a championship loss? At least they could have ended with the 1985 season.
The very first scene was Magic getting his diagnosis. I thought the show finale would bring us back to that moment.
