Love you!
To be fair, I wasn't totally joking. I mean, drama is a pretty ill formed category. Also, I haven't seen Black Swan, but if it is like Aronofsky's other films it would be, like you said, a really, really great film that I never want to have to watch again.
And on that tip, Requiem for a Dream is one of my favorite dramas, but I never ever want to see it again.
A conversation I just had with my sister:
Me: "What are some of your favorite dramas?"
Her: "Uh... Well, Schindler's List."
Me: "That's what I keep thinking too!"
Her: "Meh, I never saw it."
For the record, I thought Schindler's List was over the top.
What about Fight Club? Momento? Do those count? Eternal Sunshine comes to mind. I watch American Beauty about once a year, and I almost never rewatch films.
Can we consider the Step Up franchise drama? I mean, besides the dancing. Because I found Step Up 2: The Streets pretty compelling.
