Never liked it honestly.
It's hard to get a read on Burr. He says some super questionable shit then says something that makes him seem really 'progressive', to the point you rationalise that the questionable stuff is just part of his jock asshole shtick. Which I can't deny can be fucking hilarious at times.
Then there's this trailer which makes it seem like the dude is kind of just turning into a clueless boomer asshole. Maybe its just a shit trailer, I'll try to sit through it when it releases.
Ignoring the trailer, which is just you know a trailer, and they don't tend to be super representative of movies, especially in comedies, there isn't much to understand, you can be say staunchly against the wealthy dominating society, while being a massive transphobe, you can be pro abortion while believing in normative gender roles, progressiveness isn't a singular spectrum, it is several spectrums depending on the topic.
I mean, how many democrats push for relatively progressive policies, and then will at the same time be quite pro-Israel and their current apartheid state.
Black people in America, for example, have historically been very progressive, far more than White people, yet as far as I know, their views regarding Gay rights and trans rights and so on, aren't particularly more progressive than White people's opinions there, that doesn't mean that they as a community don't tend to be progressive, just that this doesn't apply to everything, unfortunately.
If we look further back, history is absolutely littered with people pushing progressive ideas in an area while having absolutely abhorrent views in others, I mean how many of the US founding fathers weren't espousing the relatively progressive for the time view of equal rights for men (not women though), while owning slaves themselves.
Bill Burr is very much a case of being fairly transphobic, in the sense that he unfortunately believes and espouses views that many of his peers (both in age and profession) have regarding trans people, while also being aware of certain systemic injustices on other unrelated topics and being progressive in some of those.
Anyway, don't expect this to be a deconstruction of boomer ideology, but also don't think it is just going to be an old man special, suspect it will fall a fair bit into both the sides are wacky and hypocritical type of thing, which can be made to work if it doesn't treat both sides the same (As in being performative on Twitter is not the same as being a massive asshole in real life), but doubt he will pull it off even if that is the intend, frankly his comedy hasn't been particularly good or insightful for quite a few years, something that giving credit where credit his due, he himself has said once on an interview with Conan, I think.
