None of this reflects on the actual facts of dark matter.

Most of the Holy Grails in particle physics do at least allow proof of their existence, however; most definitions I've seen for dark matter and dark energy (which mainly seems an explanation for dark matter not covering all the bases either) seem to make them unverifiable by definition (if not as badly as my favorite such example: Branes).
Most definitions for dark matter and dark energy do not make them unverifiable by definition. If that were the case, there wouldn't be over a dozen experiments trying to detect dark matter. I'm not sure why you think otherwise, but a statement like the one you made, offered with no support, lacks credibility.
Also, dark matter and dark energy deal with completely different phenomena and evidence. Dark energy has to do with the accelerating expansion of the universe, and as the video describes, we know less about it than we do about dark matter. This is because the observations that indicate its presence are much newer.
A modification of an existing theory. Maybe I'm being a little semantic here, but it doesn't seem like a revision on the order of what Relativity did to Classical Mechanics. Most of my objection really boils down to giving it that kind of gravitas; there's no reason all or even most normal matter must reflect or emit energy visible from Earth, and good reason to think most of it doesn't. If by dark matter and dark energy we simply mean normal matter and energy we can't observe or haven't, sure, I'm on board with that, but if we're talking about some exotic and unprecedented form of matter or energy I'm not convinced of the need or evidence.
Have you done extensive research into the actual state of the field and the various forms that the evidence takes? If not, that sounds like a problem with you, not a problem with the evidence.
It probably wouldn't be, and given a choice I'd prefer dark matter, but positing it as matter we can't see because it's too far away from us and/or any energy source makes a lot more sense to me than positing it as matter that literally cannot be seen, by us or anyone.
Some particles do not interact electromagnetically, which means those particles can't be "seen." We already have examples of such particles: neutrinos. Positing more such particles, given the actual state of the evidence (not just your (lack of) understanding of it), seems well-justified. No one has concluded yet that any specific such particle actually exists, because we haven't had direct detections. I'm not sure why you're so against physicists doing research in the most likely avenues. Do you think that you understand the field better than people who have spent decades studying it?

I still think dark matter's just non-luminous matter without a convenient light source to reflect.

We've just about ruled out the idea that dark matter is just non-luminous "ordinary" matter.
