Maybe a little bit cuz of the mother daughter relationship and her harming herself at the end

I thought of it too. Both movies deal with domineering mothers and mentally disturbed daughters but Black Swan is way much better film.

1000%
Even down to how Isabelle Huppert studied for a year with piano teachers prior to filming, while Natalie Portman studied intensively for a year before filming.

Well, if anything the other way round
If you google for it you will find many movie critics drawing parallels. But to be honest, this general theme, the sacrifices people make for art, how perfectionism destroys their personality and the family that creates the environment where such is thing is possible is something that has came across me in a couple of movies since.
I will now end this debate with you.
