Black Swan is intense.
It stays incredibly close with the protagonist, Nina, fantastically portrayed by Natalie Portman. She deserves all the buzz she's getting. We're with her - tight - the whole time. What she sees (whether it's real or not) we see. What makes her squirm or makes her jump makes us squirm or jump. If she's confused, we're probably confused. It's quite a feat of filmmaking - visually unique and incredibly creepy.
However, while I completely acknowledge the craftsmanship, I was incredibly on edge in an uncomfortable way from beginning to end. I realize that the viewer is supposed to be uncomfortable this way, constantly braced for what's to come, but truthfully, I find it exhausting and not so enjoyable to be so wound up.
I think I might appreciate it more a second time through when the jumpiness is neutralized. I think without the constant fear of surprise, I might better take in the obviously stellar visuals and superb performances.
It's a movie to be seen, for sure. I'm just not so sure it's a movie to be enjoyed by everyone.
