This is one of those docs that you keep the rivalries aside for and watch it for Arsène and the work he's done at Arsenal.
If you watch football, you should watch this - but it doesn't really have anything you already may not know. It's well made and offers some perspective from other legends on Arsenal's glory days under Wenger and the downfall after moving out of Highbury.
I did feel like there was something missing though. I thought Balon's doc on The Invincibles had SO MUCH more content. This doc was supposed to be that and then some more because this is about Arsene and The Invincibles are only a part of this journey. The doc really kicks off about halfway in, after his declaration to go undefeated but until then, I thought they missed the opportunity to say so much more about him and his journey prior to ARS. They do touch upon it but I thought there would be more. Compare this against Fergie doc with content prior to the treble, the storytelling was so much better.
But, regardless, by the end of the doc, you leave with more respect for the man and some life lessons for folks to takeaway. Respect and credit where it's due!
