I'm 60 and a life long Beatles fan--at least since I was 12, and I just got around to ordering Disney+ to watch this. I finished it last night and It was very interesting.
Episode 1 was a little boring at first. Creating songs from scratch must be hard and watching the sausage get made was a little tedious to me. Episodes 2 and 3 were very interesting and the ending was about perfect. Paul has always been my favorite and the first episode and half of episode 2 he came across as a prick. But he is a master at creating hit songs. Seemed like Ringo was a good guy that just wanted to keep things going. It was very interesting that the producers were planning for something of a live TV performance after three weeks or so of rehearsals (with songs that were yet to be created), and the band wasn't even sure where they would be playing. They were thinking of going to Libya at one point which sounded crazy to me.
Maybe this is not surprising to anyone, but for the entire last half of the show it seemed obvious that they all knew that their time as The Beatles was soon coming to an end. Sure, they got together in the studio to record Abbey Road later in the year but there were several not so subtle hints that they were about done as a group even after they got George to come back. Some of the songs that ended up on Abbey Road were played in Get Back.
As for the roof top concert it was by far my favorite part of Get Back. The public's reaction to what they viewed as an impromptu concert was very cool. I'm probably the most pro-law enforcement guy on this site, but those cops needed to GTFO.
Oh, I'm still pissed at Yoko. I could never understand John's attraction. I can't believe they had to include some of her awful screeching--because she was a co-producer I suppose she insisted.
