A nice episode. I wonder if this really depicts the USA or is this fiction, from my foreigner point of view, I have no idea.
It certainly depicted the trainwreck that was Woodstock 99'. it tried to put a spotlight in the bad things that made it into a shitshow the pricing, heat, filth, lack of security, etc.
Overall, it didn't do a good job showing how the rationale changed from 69' to 99', the historic context in the 69' version was certainly different, and of course it would translate into a different sentiment from the attendees. 99' line-up clearly shows how the teenage angsty was at a peak back then, dissatisfaction about society turned youngster into rioters.
Definitely on the same vibe as The Twilight Zone, Tales from the crypt, and, at some extent, Black Mirror. I wish we could have some more of this.
