Let's face it. Every general on both sides of World War II will have their detractors and admirers.
For me, I respect Rommel's military record. He did what he could with what he had. I personally believe that he is a victim of the Peter Principle. He proved that he was a good combat leader. However, when he was promoted to field marshal, he didn't have the additional training to really fulfill such a role. From what I read, he didn't had the necessary education needed for senior staff officers.
