In reality, you wouldn't have much time to get bored or sick of your new surroundings. If you read and listen to the people who spent days on the moon, which is as equally desolate as Mars, you never get any sort of impression that this how they felt. Similarly, the folks who spent months on the ISS aren't the type of people to mope and pine over luxuries.
You wouldn't want to go, sure, and you would undoubtedly experience what you describe, but there are plenty of others who would want to go and wouldn't feel the same. The first people to land on Mars will want to go and will want to be there. It will be both a passion and a job for them. And their daily tasks will keep them occupied for months and months. There will be a wide range of experiments, classes with school children, maintenance jobs, geological expeditions, gardening, rock analysis (the whole point is that you bring the man and lab to Mars, not bring the rock to the man and lab), personal research projects, photography opportunities, etc. quite aside from the fact that you are living and working on FUCKING MARS.
Perhaps most significantly, they'll be scientists working in a completely different setting doing what no-one else has done and can do. I really wouldn't underestimate this.
Also, Mars isn't like Tatooine at all. It's not just a sea of reddish rocks. There are mountain ranges, canyons, gorges, etc. It is, to borrow a phrase, magnificent desolation. The view from a rover is far more interesting than a satellite picture, no matter how HD it is, and the view from actual eyes in a human head would be even more interesting.
