I thought Other M's problem was the characterization, not the localization itself?
Other M had a lot of problems. The characterization of Samus is only the most commonly voiced, but it's more than that. As a long time fan (since Metroid NES), I was more offended by the fact that it contradicted something from virtually every game released before it. That showed a lack of polish, or plain laziness in doing research on the established canon. If you're going to tie a game in with the rest of the series, you have to be familiar with the canon from other games in that series. If you're making a stand-alone that branches off, make up as much stuff as you want.
As a person, I'm rather annoyed with the fact that this game basically romanticizes abusive relationships. Samus or not, I really don't think abusive relationships should be glorified. The fact that it is a woman who has time and time again revealed that she's physically and mentally tough, and independent makes this even worse. Even if I give the game the benefit of the doubt and say this is Samus' perspective and she idolized him,
the game failed to establish a credible reason why. It doesn't explore Samus' vulnerability, Adam's personality, or why she is drawn to him. It simply takes all of these as a given, leaving the characters with no real motivation behind their behavior. Why was Adam so determined to not let Samus use her Varia Suit in a
superheated environment where she could have died without it? Can you imagine a US military commander telling his troops they cannot use SAPI plates and helmets in a combat zone? The writers didn't even have the decency to provide some plot-related justification: they just said "that's the way it is." That's poor storytelling and characterization.
As a gamer, I really didn't like the gameplay decisions. First, there were the arbitrary handicaps (no Varia suit just mentioned). Then there were the controls. Metroid Prime Trilogy merged 1st person shooting with motion controls flawlessly. Are you telling they couldn't have done that with Other M? There was no need to bounce between 1st and 3rd person unless they just wanted to. If that was the case, they forgot the age-old saying "don't bite off more than you can chew." Devs need to make sure that they have time to refine any features they implement. They didn't do that, and the game suffered for it.
I can't speak for others, but I wasn't upset with Samus' characterization per se. She's human (well, mostly) and entitled to her moments of vulnerability. I do think her breakdown in front of Ridley was a bit over the top. Can you imagine Mario falling to his knees and weeping in front of Bowser? Can you imagine Link having a breakdown just as he's facing off against Ganon? Why should Samus have one in front of Ridley? After all, Samus is one of the most powerful gender equality icons in gaming. Aside from that, her emotional frailty alone didn't bother me. It was the whole package: poor story-telling, disregard for the rest of the series, and poor gameplay decisions all thrown together in an unrefined package.
