I'm through 6 episodes this far, and I have two issues.
First, I can't tell who the audience is intended to be. There's almost no context to allow someone unfamiliar with this team over the last 25 years to get a good picture of who the Patriots were during this stretch. They basically only introduce two players: Brady and the QB he replaced (Bledsoe). They don't even bother telling us about how awesome the defense was in those early years. They interview a couple defenders, but don't show their abilities; they're only there to tell the story of Brady, Belichick, and Kraft. There's no details during games like score, stakes, down, nothing. There's no sense of the importance of any game whatsoever. Even the undefeated regular season in '07. Wouldn't it make sense to mention that only one team in the NFL's history ever went undefeated and won the Super Bowl? And it's not like they ran out of time - episodes 5 and 6 are 30 minutes each.
Second, it feels like it's very biased towards owner Robert Kraft. In episode 6 (focusing on Aaron Hernandez and being charged with murder), at one point they basically insinuate that if Belichick had traded Hernandez to the west coast (as he requested), that the whole situation could've been avoided. If anyone's unfamiliar, there's been quite the rift between Kraft and Belichick the last few years.
So the tl;dr is that this feels rushed to get it out right after Kraft fired Belichick, and as a result of rushing, lacks a ton of fundamental production/editing qualities to make this hold up to any of the recent docuseries. Maybe it needed 10 years to have a better perspective on the whole thing. Too bad.
