I believe it is very relevent to mention the main reason why I love Charlie Kaufman's writing so much; and that is because he tends to write his main characters as strange, socially awkward, self-loathing outcasts, which is what makes them so understandable to me. That being said, I also found Being John Malkovich to be a hilarious and stylish study of the intricacies of the human psyche.
Not only does the film perfectly portray what it would actually be like to see the world through someone else's eyes (literally), it also subtly questions the role of the human mind and soul, and what seeing something like this might do to one. Spike Jonze's direction is superb, and I finally see why he received such accolades for the film...I found this to be even more enjoyable than the also superb Adaptation, the other Jonze-Kaufman collaboration.
John Cusack was surprisingly awesome in the main role, as was Catherine Keener as his seductive business-mate. John Malkovich is, of course, the man, and convincingly played himself, and John Cusack's character, and Cameron Diaz's character.
I was extremely surprised at how much I loved this film, but I guess I should have seen it coming, since I typically am most intrigued by absurdist fantasies. But this one is even better than others.
