People writing bad reviews based on their dance past may have a point, but might be viewing this from the wrong perspective. Yes the show is about a ballet company, but it tells a story, more than one actually and even if there are clichés in it, that's called dramatizing the story.
What is being told here could have used any background. Look at 'Mozard in the Jungle', that setting could have fit too. Yet, finally someone takes courage in making a beautiful show with ballet as background. Shouldn't you people be proud of that instead of pissing on it?
For me, I love ballet, but that's not only the reason why I'm watching and I never really leave reviews here, but reading from 'ex-dancers' I thought it felt unfair how the show was being reviewed. The acting is very good, esp. from the lead, the dancing imo is good enough to fool the audience and it's the whole vibe of the show (the way it's shot, the music) that sets a really pleasant tone to watch it. I am kinda sad there aren't more episodes, yet.
So, watch it, don't judge too soon and enjoy it. It's like reading a good book!
