O.k., if you want some more detail to the criticism, fair enough.
I thought you interrupted far too often. Breaking up the flow of the interview. When watching an interview, I prefer to be able to hear the interviewee, not the interviewer.
In addition, the interruptions were (to me) unfunny side comments that didn't add to the interview, and were frankly annoying.
Now, on the other hand, you could have stated in the first place that you didn't think the comment added anything or wasn't 'positive' criticism. I don't believe the solution in situations like that, is just to automatically accuse someone of trolling.
If you do get numerous postings which express similar sentiments, maybe there's a reason. I'd want to know why.
