The debate was suprisingly good, albeit this might be due to contrast how bad the previous one was.
I liked that moderators were flexible, but orderly - they allowed enough rowdyness to keep it spicy, but not too much to turn into cacophony.
Another nice thing, is that both Trump and Harris toned down on this peculiar fake manner of speaking, that is seen among many present day politicians.
Trump manage to tone town that "car salesman" way of speaking, but he still repeats himself and drift waaaaay too much.
Harris on the other side, while being a bit stiff at the beginning, clicked well in the second part - it felt like She dropped the prepared script and went full relaxed and natural - I wish we could see her in such form more often.
As for Trump pets remarks, it could feel weird, it could feel funny, but somehow it reminded me case from 10-15 years ago when Polish immigrants in London ate a swan (and no, this would be frown upon in Poland, we don't eat swans normally

).
Overall, I'd change one thing in the debate:
I wish there would be one anti-Trump moderator and one anti-Harris moderator, who would have a right to scream "OBJECTION! DEFLECTION!" every time they try to drift away and not answer given question.
Both Trump and Harris had such moments, albeit Trump had more of them.
