(Sorry for the above being sent multiple times, I had a network issue.)

You're suggesting larger changes to the title. I'm only saying 'this phone' should be replaced with 'the pixel 69' or whatever the model's name is. 'The pixel 69 is almost perfect' is short, informative (edit: by which I mean informative enough about the video's topic), more informative to anyone that hasn't seen the phone before, and draws people in: why's it almost perfect? That's worth clicking to find out, and the details aren't something you'd expect someone to cram into a general review title.

I fully agree that the title should encourage people to keep reading, but in my opinion 'basic writing' is keeping a balance between both goals of a title. The examples of clickbait I've given involve people optimising the title for attracting views while neglecting the goal of reasonably accurate description. If taken too far it could start making viewers feel patronised, and if I encounter a video with misleading clickbait I assume the rest of their videos will waste my time as well and avoid them. (Edit 3: I increasingly assume the same about vague titles from unfamiliar channels as well.)

If your thesis statement is the entirety of your argument then you are wasting everyone's time.

The last part of my previous comment was about this; maybe we're miscommunicating by using 'summarise' differently, as in 'covers every point' vs 'vague overview'? I've been saying titles should do the latter because that's what this entire conversation has been about. Nobody thinks every point of a review should be included in its title, just that the title should be reasonably descriptive about the central thesis or central question being explored. Quoting myself:

A good video doesn't just repeat different wordings of the title for 10 minutes, it goes into specifics to argue why that is.

the video would only be bad if it can't argue [the title's statement] well or has a lot of fluff between the points.

TL;DR: there's a balance to be struck between making the title descriptive and drawing clicks, and talking about full summaries as titles is a bit of a strawman.

EDIT 2: Removed some italics because they made this sound unintentionally patronising. Apologies, haha.
