i'm seconding "i saw the tv glow". i watched it once. i don't think i can stomach watching it again, and that's a compliment; it's a horror movie and it succeeded in horrifying me. but it was also something of a wake up call. i'm doing my best to live my life to the fullest now.
i think this fits the category... one of my favourite pieces of art ever is "angel's egg". it's a collaboration between yoshitaka amano, best known for his work on the final fantasy series, and mamoru oshii, director of 1995's "ghost in the shell". if i had to describe it, it feels like a dream, and i really don't say that lightly. little of it makes sense. there's almost no dialogue. there's not even really a plot. it's almost ambivalent to the idea of an observer, i suppose. but it's beautiful, and i find it interesting to consider the meaning even if there isn't really supposed to be any.
