Nowhere near on the same level as Spike Lee's previous Bad 25 documentary. This is more like a rehash of an existing 1988 well known documentary called The Legend Continues and uses a vast amount of existing footage from those interviews, including from the same talking heads conducting new interviews for this production.
There are a few instances with rare and good quality tour footage from the Destiny and Triumph tours from The Jacksons, but I can't help but wonder why more than half of the running time focuses on Motown, without going in any great depth on J5's music - choosing instead to tell us the same story that has been done a hundreds times before.
It makes no sense to do a faux focus on Off The Wall 36 1/2 years after release when the better project would be to do Dangerous later in 2016 for the 25th anniversary. Considering fans have very little footage and not a lot of insight into that album - being more recent, the influences and collaborators are likely more readily alive and available to talk. I'm sure Teddy Riley etc. would be preferable to getting overused stock footage of Quincy Jones who is reluctant to discuss his time with MJ these days anyway.
