You're in for a treat, especially if you can enjoy the 70s stylings of James Burke. I particularly enjoy his dry wit which would probably be toned down quite a bit for modern serious productions.
> the usual 'woke' rewriting of history & present
It's not so much rewriting (unless you're a publisher looking for free publicity), but attempting to not broadcast very offensive material that was considered normal back in the day (much as slavery used to be considered normal). Personally, I was quite a fan of "Till Death Us Do Part" featuring Alf Garnett as a racist bigot, but then I can appreciate irony and that the programmes were making the point that he was a character to be lampooned and pitied. However, there's too many people that would accept it at face value and use it to justify their vile racism, so I can understand that it's not suitable for modern consumption.
If they just put up everything they already made they could charge more than Netflix IMO. Instead, god knows why, it's a limited selection that too from which some missing episodes due to the usual 'woke' rewriting of history & present (racist or whatever-ist people exist right, so what's the problem with a show having such a character? Doesn't mean it's right, nor that the show itself is that-ist).
