How to read/react to students' evaluation?
I spent many years of my professional life discussing how to present complicated ideas. The first rule that I developed was: "Any comment, however stupid seeming, should be taken seriously". In the OP's context that means try to understand what the student comments are getting at, even if the students who are commenting cannot explain it. Something you said evoked that comment. If you don't like that comment say something differently next time.

The second rule is: disregard any specific suggestion for how you might say it differently. Only you know what you want to say. Your students do not.
