Repetition Good or Bad

I noticed the following post at Ratemyprofessor.com about me. I beleive that repetition of important concepts helps the students but they dont seem to like it.

very clear and helpful, but goes over the same thing too many times so class gets a little boring. he wants students to learn, not just meet requirements, which is refreshing. he does sound a little like the count.. perhaps we could try to guess zee number of zee day? hot.
