I tried shooting landscapes on 35mm film. I gave up after about 6 months. 35mm would be okay for posting landscape photos to Instagram or printing postcards (if people still do that), but it's generally not a good format for serious landscape work. The thing with a landscape is there's usually tons of detail all over the photo that you'll want to draw the viewer's eye to. Landscape photography isn't usually about just one object, but rather a collection of many shapes, textures, tones, colors, and atmosphere. It's a place for the viewer to become immersed in and encourages discovery and inspires a sense of wonder. Small prints of landscapes don't really impress most people. They need something bigger that they feel they can enter. It needs to feel real to them. I couldn't blow up a landscape photograph large enough (at least 8x10) without exposing the grain. And seeing the grain in a landscape photo destroys the illusion.
35mm is great for street photography where the grain of the film can add to the grittiness of the modern world. It can work for portraits because you don't need to see the detail of every pore to have a good portrait. They can work for abstract photography and many other genres as well. But landscape photography (and often architecture photography) is where the limitations of 35mm film get in the way. For landscape photography, I only really consider large format or digital, and sometimes medium format. Others will disagree, I'm sure. But you really need the right tool for the job, and 35mm isn't the right tool for landscapes. Just like 8x10 isn't really the right tool for street photography.
