I'm among those first in line to give Other M its due criticism, but I do think we (as in, Metroid fans in general) should aim to avoid presenting it as the go-to example of what to dread, and what simply doesn't work in Metroid, in cases where it isn't entirely fitting to. I've seen folks invoke the disaster of Other M in order to say overt storytelling in Metroid is bad thing, and the same with characters, Samus talking, the series being in a third-person 3D style, and so on. There's a contingent of fans that seem to believe that just because all of those things were most prominently featured in one game, and that the game was reviled, it means those working on the series best not try those things ever again. Thing is, Other M wasn't rough because it had characters, a third-person 3D camera, or Samus having her face prominently shown. It was rough because those happened to be elements that comprised the greater whole, and because of that negative association, folks are now excessively apprehensive about the prospect of those elements ever returning again.
