Watched The Four Falls of Buffalo on the DVR this morning and I thought it was better than the 30 for 30 episodes that are produced by the league that's being discussed. Usually when you see NFL/NBA/MLB Films Presents, you're in for a lesser episode but this was pretty solid. Not one of the best but solid. My only complaint is it felt really padded out at two hours and would have been much better at 90 minutes.
I think the Bears 30 for 30 could be great if handled well. But again, assuming that this is an NFL Films Production, they're gonna sort of whitewash how depressing a lot of the guys' lives were post-retirement (even though the trailer did allude to Jim McMahon & Fridge's health problems).
