The Lecturer is brutal. the "Umm" rate in his talks is inexcusable for a professional public speaker, which is what I classify any "teacher" as. Makes the lectures impossible for me to listen to.
I'd take a trained speaker–even an actor who doesn't actually know the material he/she's describing–as a primary lecturer any day, as long as I get access to someone who knows what they're talking about in a recitation.
I am not a good speaker, but one time my employer offered an hour long session with a coach before a conference. I presented my material (something they strongly emphasised) and he was able to give me advice on getting rid of the "umms" and sound a bit more engaging. It made a big difference to what people have to listen to and gave me a confidence boost.
If you can't listen to it - maybe that says more about you than him?
How is that a meaningless criticism?
For lecturers the ability to present in an engaging manner is at least as important as understanding the subject.
The reality is that you are just being mentally lazy for not accepting new information because it isn't in the most palatable format.
It is juvenile.
