It's quite interesting to see the various different views on this. I wonder what Boogie expected the reaction to be, because I can't help but think this is more his film than the guy who recorded and edited it, and I think that's to a fault, unfortunately.
I think there's probably a good story in there, a number of them even, but too often the difficult questions don't get asked or you're left to fill in the blanks. Perhaps because of it's extended gestation, the scope feels too big - you could make an entire film about just one particular aspect of his life or events.
You could have made an entire film leading up to and the aftermath of his fight, for example. Instead that's practically breezed past. Who was he fighting? Why is he doing it? How did it come about? Who went to see the fight? What did they think? All of those things could have been very illuminating in finding out what people think of him, his attitude to an opportunity to make money, where he views his place in the world, his attitude to performance, what he thought the fight represented, etc. etc.
Overall I don't think that Boogie is necessarily a villain (but he's no hero) but I do think that he's aware of an audience and trying to work out how to appeal to it, or make himself a sympathetic character and it's not worked out so well, based on reactions here at least. His ego shines through in various moments too - most notably the skin crawling moments with his girlfriend, especially when they reveal how great their sex life is. This in a film that tells us sex with him was so revolting it made a sex worker turn her back on the job. That stood out to me as a particularly weird moment that doesn't fit with the narrative, but it does speak of someone who wants to be pitied, but whose ego won't give up some things completely.
I imagine purely in man hours that the investment in recording and editing this was significant. I'd be interested to know how involved Boogie was - did he have sign off on the final cut? I assume so.
it's a sad tale, of course. Most reactions will focus on his weight and it's impact on his life and health, I think, which gets a relatively high amount of screentime, but the most interesting things in finding out who Boogie is, basically are left to the audience to guess at.
