I think it's an accurate description that successfully conveys the manipulative, puerile, and harmful nature of these shows in a compact way. My description isn't political in the "right vs left" sense although I admit it may be political in the "extremism vs moderate" sense. Personally, I think that the information we consume cannot help but shape our world-view, so identifying how it shapes our world-view is valid criticism. Reacher and Galadriel are, in my view, icons of their respective flavors of extremism, and I think Amazon does poorly to produce such content.
Have you actually watched Reacher? There is no politics in it at all. It's reminiscent of poorly written 80's action flicks, disguised as a noir mystery.
Again, sometimes bad television is simply bad television. Not everything needs political coloring.
"Ex-military strongman solves our problems through murder" is an inherently political framework for a story. It is as politically tainted as the old show "24", where any and all ethical frameworks were shredded on the altar of the ticking bomb scenario.
That the maintenance of the rule of law requires One True Man to stand outside the law and protect us through extrajudicial killing and torture. It is a statement on the core concept of law and justice.
