Although this is pitched as a documentary about Abbey Road, I think it is much more "simply" a documentary about how music is made. And it is a very informative documentary about how music is made. So if you have an interest in music, but no specific interest in Abbey Road, do give it a go. I doubt you will be disappointed.
Even at "only" 90 minutes, this documentary is perfectly paced, with unrushed recollections from many musicians.
I'm not sure it's worth subscribing to Disney+ purely to see this, but I found it to be one of the more interesting things they had to offer in January 2023. Hope you enjoy it too, if you decide to give it a go.
