It's good, but the main criticism that it usually gets, and that I think is totally valid, is that it is (surprise, surprise) east coast centric. He spends an enormous amount of time on the Yankees, Giants, Dodgers, and Red Sox, and very rarely goes into any detail on anyone who played elsewhere. For example, in a 10+ hour documentary about the history of baseball, Rogers Hornsby gets a total of two minutes and thirty seconds. Ernie Banks and Frank Robinson get less than a minute. There isn't a single mention about the 1969 Cubs, yet there is over 10 minutes about the Miracle Mets. Furthermore, the diversity of his guests was lacking. They were nearly all New England elites like Burns (George Plimpton, Doris Kearns Goodwin, Daniel Okrent, Robert Jay Gould, and a few others). However, he did have George Will in several segments, which was great. Also, Mike Schmidt is not mentioned at any time during the whole series. My favorite parts of the documentary series are the first two chapters. I'm fascinated with 19th century history of the game. When I visited the Hall of Fame in Cooperstown four years ago, one of my favorite exhibits was about the old National League. They had a baseball used in a championship series in 1888, I believe. They used one ball for the entire thing, and on display it was all misshapen and lopsided. I thought it was the coolest thing ever.
