My only real qualms with this were the ending (which I can blame the original author for, rather than the series writers), the weird decision to make many of the characters bisexual, and the excessive dreamy scenes others mentioned with birds or blurry imagery meant to take up extra time. Aboriginal descendants were in the film (though that may not be historically accurate) and brought up frequently enough in regards to Hanging Rock that I thought they did a decent enough job to avoid complaints about that.
Other than that, without having seen the original version or reading the novel, I can say that this is a show worth watching, and I didn't regret it. I really liked nearly all of the female central characters, and thought they did superb acting jobs. I also thought the character development was pretty good, although it could have been a little better in regards to Sara, whose character was one of the best.
I really liked the theme of the show in regards to true freedom, and the idea that some birds just weren't meant to be caged.
On a side note, it's sad but interesting that Amazon won't allow anyone to review the show on their website as of 6/9/2018 due to negative reviews. What a shame.
