On film, You've got only one opportunity to take the shot, I've made few Superia 200/400 films and am so unhappy about it!! Crappy colors, bad resolution - some shot woul've been great if they were better quality.
You can buy expired films like Reala, Portra etc. and they still will be better choice than cheapo stuff. You can always alter Your pics, but You just can't make them better if shot on wrong film.
