I mean, aside from some of the Kung-Fu scenes, what was not accurate about it? (although people did excel at Kung-Fu, maybe not quite to that level, but they did).....People from that time era speaking English?

, the acting and production, i thought, portrayed the overall feel of the time era to be accurate.
Portraying "the overall feel and time of the era" is not equivalent to being historically accurate.
I'm fairly generous when it comes to fiction and will ignore the usual quibbles that people have about films and shows (you know the amateurish arguments about "plot holes" or "lack of character development"... yawn). I take each work on its merits and what it set out to achieve. I enjoy my share of kungfu films, especially Bruce Lee classics or
Master of the Flying Guillotine - I look on them much more kindly than, say,
Interstellar, which has other pretenses but fall short of its own ostensible goals (unless that goal was simply to bamboozle audiences and/or make money - but I'm not that cynical).
I even liked
Braveheart, as rubbish as it was historically. But I'm under no illusions that I can expect this series to be more accurate than that, even in its depiction of the "feel and time of the era." The whole kungfu and Orientalist flavour of the series
does detract from the time and feel of the era, especially because it builds on tropes about the Far East that was constructed for the benefit of Hollywood and its Asian equivalents. In other words, it's what modern audiences like MobBoss enjoys and thinks about Asian culture.
There's a
plethora of films and shows that depict the feel of East Asia more accurately, sans kungfu or ridiculous gun fights, even if they do rely on their own tropes (see
Infernal Affairs, for example). This is probably not one of them.
I'm always shocked at how so many Westerners buy into the whole "Oriental Shaolin Superman" nonsense. Kung Fu is not even a particularly effective fighting style (Kung Fu practitioners always got a massive ass-whooping on MMA competitions and don't even bother to try anymore). But even if it was a super effective fighting style, which it is not, it still wouldn't make you capable of wiping the floor with dozens of heavily armed professional warriors who are stronger than you.
'Kungfu' is not one thing - that's a modern invention. There are many types of kungfu (which literally just means 'martial art'), like Wing Chun, Jet Kun Do, etc. Some of them are quite effective too.
