His points about the analysis community being "oversaturated" are spot-on, and one part of a reason why I don't do videos. Another being the possible price of fame. Imagine what kind of bridges Tommy Oliver may have burned by scorning his fanbase like this.
Following his advice, I won't post most of my thoughts here because either ToonKritic already expressed them well or others will inevitably get to something similar. I'll admit to a little bit of confirmation bias myself, and I present the reason for that as looking to people who have a talent for expressing their opinions better than I can to express my opinions for me. It's natural to gravitate towards people who share our opinions. The problem is that we should not be so dependent on these people to do our thinking for us. They're enjoyable to watch and talented people, but that doesn't mean we're any less of people than they are.
As for the tone I'd deliver, ToonKritic pretty much says it, and my review blogs pretty much say it. Structured, concise, with every point clearly marked. However, I'd occasionally slip a little joke into the review every now and then to keep the audience engaged, because we all know strict formatting is boring without a little flexibility.
I consider all possible, founded arguments. One of the negative points of many analysts is that they get too passionate about the show, intensely fanboying over it when it does good and intensely trashing it when it goes wrong. Everything right or wrong about the episode, in my style, is examined as well as its real-world implications, and suggested with a possible alternative route.
Finally, chief among all problems is that some have expectations too lofty for the show. Oliver's expectations of the show used to be more realistic; slice-of-life with a fantasy component. However, something changed between seasons 4 and 5. He got jaded by his viewing of anime and other cartoons like Digibro did and it led him to unfairly expect an airtight plot and continuity from this show. For me personally, I expect a great moral and message and a plot not airtight or with the complexity of a crime drama, but sound enough to support the delivery of the moral without marginalizing or contradicting it, or going back on its characters. The subtext and humor is all excellent when it's there, but it's a bonus as far as the overall structure of the show is concerned; something even the writers don't get at times.
Everything should be considered fairly and equally if backed up by the adequate amount of evidence. Fanboyism and experiences with other shows shouldn't pollute our vision of MLP and what it really is. Most of all, fans have a responsibility to think for themselves and not externalize their problems on figures as known as the analysts.
