I work with post production for tv/movies. Current digital sensors are much better than film in clarity, noise, dynamic range, etc. Film is still, arguably, superior in look.
The noise inherent to film. Aka film grain is more irregular than digital sensor noise and can be more pleasing to people. People have argued that part of this is familiarity. People who grew up watching film have a large base of memories and associations with their favorite movies and the 'film look'
IN vfx work we use a large library of film-stock grain patterns to add noise to cg elements.
