As long as you're not expecting fresh-off-the-shelf perfection, it's all good. Black and white stuff seems to last almost forever, though it does lose speed -- bear in mind when exposing. There are varying opinions on processing regimes, though I've found the base fog most manageable (at least for scanning) with normal processing. I have my film commercially processed and don't tell them to do anything special. As long as the exposures are good, the stuff looks fine.
Color is a mixed bag, thus making it an unpredictable ton of fun. Any C-41 negative film can still be processed, as can E-6 chrome. Often the most interesting results with old E-6 can be had by cross-processing in C-41, then printing/scanning the resultant negatives.
Film calling for old processes (C-22, E-4) are almost impossible to deal with except for a couple of speciality labs that charge a fortune and take forever. K-14 Kodachrome in any size other than 35mm cannot be processed anymore.
On the old black and white front, here are a couple of recent shots on 1970-vintage Ansco All-Weather Pan:
