If it's C41, that's a major reason serious photographers often used E6 back in the day. Labs could not print well using automated equipment. So unless you hired someone else to do custom reprints, you didn't know if it was the lab screwing up your prints or if you were inept at color photography. E6 was wysiwyg, but has other constraints.
Development for C41 should be completely automated and little opportunity for them to screw it up, aside from scratches and dust. You may have to scan them yourself or find someone else to print the good stuff. Even most automated prints these days are made from scans, which are very subjective and subject to the dichotomy of good versus cheap/fast. I pay a local lab $5/roll to develop my c41 film, then I get to scan it, print it.
