I find it very easy to use: Just shoot and enjoy!
If you want to shoot a gray wall, well then, every technology will do well and you can go even with digital.
But, if you want to capture the natural light when it's at its best, the only way to go may be (neg) film. For example, a forest, where sunlight comes as millions of tiny rays. I have yet to see a digital image capable of reproducing these kind of lightning conditions.
Although being quite rare situations, they are the most beautiful and very sad to miss due to technology.
