The Happy Days of Garry Marshall

It's a network TV doc of the late legendary TV and movie creator. The stars of his shows and films sing his praises. There is a sprinkling of behind the scenes. Mostly, it is the most Garry Marshall documentary of Garry Marshall. It is nice. It's a little fun. It's nostalgic which is very good for pandemic watching. It's empty calories. There is nothing to be learned other than that he's a super nice guy. I think we knew that already.
