I like film because I like film, that is reason enough after all. Since I am not photographing for an employer anymore; I owe nobody any more explanation than that. So, I still shoot slide film and black and white when I shoot trains.
What do I like about film? I like that slides are tangible, I can scan them to a 16 BIT Tiff and do everything with it I can do with a camera RAW file and still have my slide. Slides have value, you can trade and even sell them. I like the discipline of shooting film. I like not having to worry about dust on my sensor if I change lenses in the field. I like that if I want higher resolution I can rescan my slide again. I am not locked into the resolution of the camera. I like that I can use my camera even if the battery dies. I like not having to worry about recharging my camera.
I like the way film sees light. I like that I can change the personality of my camera by changing the film I put in it. I like that bright red railroad signals stay red and do not turn white if I am shooting into them with film. I also like the smell of film and the sound of a Nikon motor drive.
I like that once the picture is on the wall it really does not matter if it was shot in digital or analog anyway. So, even though I have and use a sweet digital camera, I find a lot to like when I shoot film. So, I still do.
