I've spent a lot of time on this in the past, but not recently. I'd guess you'll get something out of it, probably not good.
Scanning negs & slides requires a high quality scanner, decent software and a lot of skill. Unless you're very lucky.
Prints and slides are a lot easier. And slides also need a high quality scanner. But there's still a lot of work involved in getting the colours right as the fading isn't consistent across the dyes. Some slides, like Kodachrome, hardy fade at all, but a badly processed E6 slide film often has as serious colour issues as a print.
Negs seem to retain colour better, but... there's always the colour mask to mess you around.
Personally I wouldn't bother. But it may surprise you.
