For me it is the whole process, the careful composition, the waiting for the processing, the expectation building, the boring scanning, then the fun playing with the digital images in the digital darkroom.
Crazy - if I wanted digital images, why not just shoot digital?
I tried that for a while and my photography just went trivial. Like on holiday late last year watching a foursome of young people at a table in a restaurant each with their enormous DSLR's with massive glass on the front. They sat there and photographed their plates of food as they were served, and then looked at the back of the camera as if the picture would look somehow different from the food they had just photographed!
I found the same with digital, looking back at the images I took in those years, they were just rubbish, odd shots of my wife, mundane subjects I hadn't bothered to compose. Film just makes me focus on what I am doing and makes me try to get a better shot as film costs money and effort.
I sometimes wonder - TBH, my Opticfilm 120 is playing up at the moment, I have learned much more about Photoshop and scanning by scanning in all my old film, so am contemplating going through all my old film and scanning it in again and doing better with it this time around. Crazy, what!
Film keeps me off the streets and away from doing anything worse, my wife is happy with that, it's a quiet life.
