The first big problem with film was always that you ran into crossover problems; ie, when you corrected on the magenta-cyan axis it made it worse on the yellow-blue axis possibly. There were even worse problems. In the end, you really couldn't correct for everything everytime in any way. Also, the spectral response of film was often not that good once you got out of the exact lighting the film was designed for. No film was good for fluorescents, because film is designed for certain types of continuous emission spectra, and fluorescents just don't have those. Digitally you can easily create response curves that go up and down, have spikes or whatever. Plus you can to local corrections. Way easier.
