This is somewhat of a good point, I like film's aesthetics too. But, grain and noise are two different inter-related things.

A digital full-frame sensor (vs 35mm film) at the same settings is going to have much less noise. I love film. But the fact is that silver vs cmos is a losing battle of technologies.
