Expired films often produce interesting results. Not right, but interesting. I don't necessarily look for that in the film. Of course, disappointing results are often obtained. For this reason, in general, expired films are not suitable for work. But for the hobby - why not.
For home development - it's really a good time to gain experience. Yes, with a bad result, it will be unclear where the problem is - whether in the film or in the developing process. In fact, some kits on the market don't perform very well. But as already written – the process is actually very simple. You just have to follow the instructions. No special expensive equipment needed - just a sous vide heater for precise temperature control. As long as the times are respected - the procedure will be fine. Either way, even if you give these films to a lab, the results will most likely not be good. For acceptable results, one should start by applying the appropriate (for each individual film) overexposure during shooting. Of course, without any guarantee...
