Kill Your Darlings is a fantastic film. Your review is good, my only criticism is that you mention Ben Foster as playing a "drug addict" without mentioning that that drug addict is not just any old drug addict, he's William Burroughs, the drug addict.
I also believe that Ben Foster as William Burroughs is the stand out performance of the whole film. It really makes me wish that Krokidas would adapt Burrough's Junky with Ben Foster as the lead. I think that would be absolutely fantastic.
You have some very interesting points! Thank you very much for reading my review thoroughly.
