Metroid: Other M stands to he the worst rated entry in the franchise, only followed by the most unnecessary entry in the franchise being Federation force. Which is a shame, because Federation force had some of the best FPS controls I've ever used on a game on a handheld system.
Other M's problem (among many) was that it tried to have its cake and eat it, too. It tried to say it was a Metroid 3.5 (between Super, and Fusion) and act like an origins story. The manga did the origins story earlier and better. So did Zero Mission as a remake of the first game.
Other M is to the Metroid timeline the way Prometheus and Alien Covenant are trying to shoehorn into the Alien/s timeline; in that said entries break continuity hard once examined under any context or scrutiny against the other, established entries in the franchise. The only way for Other M to be canonical, is if it's following a timeline where Samus failed to rescue the animals at the end of Super, because those animals are instrumental to the events of Fusion. And if we take that consideration, there are still things that leave gaping, unanswered plot holes. And of course the contempt that Team Ninja has for female characters. And the horrendous voice work for Samus herself. Or the arbitrary locking of, and awkward timing of when abilities and upgrades are unlocked. Compared to literally every other highly acclaimed entdy in thr series, Other M is a bastardization.
Back on topic to Pokemon, the problem with Sword and Shield is, among many others, data mining proves that Game Freak is blatantly lying to its english speaking fan base, and outright omitting details to its Japanese players. About the only thing worse in recent memory that compares, is the unending fiasco that is Bethesda's Fallout 76. Allowing Sword and Shield to get away with this success, is like allowing that same level of gross incompetence.
