I love the sports documentaries of the ESPN series, they tend to be great, not just good. Here you great great images, goals, a serious account of his career. But I couldn't avoid being extremely irritating of so many excuses from the people interviewed, to justify his off-field very poor decisions.
"Oh it was the 60's..."; "Why wouldn't he drink, he had money!"; "He was just 19..."; His family didn't have the greatest of structure, the pressure is to great, people expect him to play well every week... yada yada. If you want to tell the story of a guy like Best, you have to tell it like it is, no concessions.
Maybe, just maybe, he was a bas***d off the field, maybe he had his demons, mental issues that nowadays are better understood, but it won't work well. I think there is an attempt to justify what you don't have to.
It's an objection to the angle taken here, it doesn't discredit the documentary, well produced and rich in material. Many might not be bothered by what bugged me, I can certainly see that.
