I think forms can be a good training tool. Like Ashe said, they're a good way to check yourself. They also provide a means of practice when you're by yourself. I know that I don't have continual access to practice partners, so solo exercises and form are the brunt of my practice.
The downside to forms is when they're used improperly. Just like using a wrong tool for a job, using forms incorrectly gives poor results. Performing a form mindlessly without any understanding of the body mechanics or attention to the movements is pretty much useless.
