That's kind of making the argument "your nostalgia is wrong, my nostalgia is right", though. I mean, in what world were the Showtime Lakers underdogs? Since when was Magic Johnson a paragon of virtue? You can talk about other people having rose-tinted glasses, but fair go, you've got some purple and gold blinders on, too.
Don't get me wrong, I'm not saying MJ couldn't be difficult (to put it diplomatically), nor that he appeals to everyone and everyone should like him. It just strikes me as weird to be anti-Jordan because you're pro-underdog, but at the same time pro-Lakers, who historically have rarely (if ever) been underdogs. I mean, with their dominance over the years, I'm sure there are people who feel about the Lakers and Shaq, Kobe, Magic, and Kareem, as you do about MJ and the Bulls.
It sounds like you've made up your mind about MJ's character a long time ago, which you're entitled to do of course, and so the documentary obviously isn't for you. It is nevertheless one of the best sports documentaries ever produced, and it's commendable that it does cover aspects of MJ's personality that are criticised and not necessarily admirable across the board. Admittedly it's sometimes hard to reconcile that stuff as a fan of his, but at the same time, it's not the whole story of who he is; people's personalities aren't stock pro wrestling faces and heels, after all. I also think it would be naive to suggest that people who are held up as being nicer than MJ are without faults of their own, or are necessarily as nice as they seem. They all benefit from good PR, and time helping us to forget some of the bad stuff.
In any event, I haven't finished it yet, but I've really enjoyed it so far. Not everything is a revelation, but again, it's been a well-produced documentary with tons of great highlights if nothing else.
