I'm afraid whatever info this documentary contains is obscured by the rather awful production values of this documentary. Odd cuts, strange 1-second flashes on other images (that is not intended as some "psychedelic" style choice), and even one fully minute or two long section where the person speaking is not visible due to something obscuring half the frame (again, not a style choice, but simply horrible production).
As for the content, the film spends the first 2/3 of the film focused on the first 2 years of their career...which would be great if the documentary was couched as specifically being about the Syd Barrett years, but then speeds through the rest of their career. And while it does so, it very agonizingly mixes concert footage from their later years ("Momentary Lapse" onward) over narration discussing their still early years. If the viewer isn't already familiar with and a fan of Pink Floyd, you would be left with a very odd and uneven (mis)understanding of the development of the band.
Also, and I can't say this is necessarily an objectively negative quality like the above complaints are, but the film is almost entirely interviews from people who hung out with Syd and Roger in the early days. This is somewhat interesting and a new take, but gets rather played out pretty fast with a lot of redundant and repetitive (heh) information and sound bites.
All told, it's a rather embarrassing endeavor. It reminds me of writing an undergrad paper at 8pm the day before it's due and spending the night focused in great detail on 5% of the topic before realizing at 7am I need to cover the other 95% of it...and then not giving it a single proof-read before handing it in.
