Is the new Tarantino film Once Upon A Time In Hollywood going to REALLY explore Hollywood?

As in The Epstein Island experience?

Note last scene of trailer: a young girl whispers to DiCaprio who bursts into tears and then pulls the hammer on his gun. https://www.youtube.com/watch?v=Scf8nIJCvs4

Note that this is the first film where Tarantino doesn't have Harvey Weinstein steering him - meaning he is free to film subjects he may have been banned from before. (What subjects would Harvey want as taboo hmm?)-

it is confirmed to include murderous pedophile (raped 14 year old) cult leader Charles Manson, but I suspect it's going to go a lot further - and do to Hollywood pedophiles what Inglourious did to Nazi's and what Django did to Slavers.
