Should look good on your CV, too! I like hearing that students actually give positive reviews. Seems like most of the time we only hear the negatives, so brag away...humble or not.
Most of the complaints I see are things like:
"I wish the semester could be longer. I don't want the class to end."
"He doesn't teach my other classes."
Something people miss: The complaints usually have some merit. One student noted that we should have assigned fewer readings, and they're right. It was more than we could actually deal with thoroughly, so we'd skip some.
Otherwise, sometimes the complaints mean that you're not very good at that part of the job.
