There's good and bad things about this documentary. On the plus side, there's quite a few interesting interviews with people who worked closely with the Beatles. On the downside, there isn't really an interviews with the Beatles themselves. And what footage there is is clearly from TV at the time, and the sound quality is often poor. And, although it talks in detail about what the Beatles were doing around the time of Sergeant Pepper, it doesn't really go in to any detail about the sounds, or the album itself.
I thought this was going to be about the making of Sgt Pepper but it turned out to be a lot of interviews with people loosely connected with that period but not necessarily in the know. There was far too much about the Maharishi and the suicide or not of Brian Epstein and also the American tour which happened years before.
One of the extras I thought might be interesting was an interview with the Bootleg Beatles which was unfortunately marred by not being able to hear the interviewers questions.
I would rather give this no stars - a cheap con.
