The best part about negative film was infinite reproducibility. The best part about Polaroids or instant films was instant gratification. Digital photography seems to be the best of both worlds, instant gratifications reproduced infinitely. We see our shot right away in the LCD screen. We can print as many copies of a .jpg as we want. But what film has and digital lacks, is a sense of authenticity.
Digital has a sterility to it. Pore-less skin, porcelain eye whites, perfect exposures, geometric compositions. I feel more attached to my post-processing software than my digital camera. I capture a moment with this tool, but I bring it home to create my image. Film photography is so much more visceral and immediate. And nothing exemplifies this timelessness of photography than with instant films.
