Samus was never really a character other than being a figure in a spacesuit with a gun arm that is revealed to be a woman at the end of the first game. Link and Mario aren't really characters either. They come from an era where the story telling in videogames was limited. As a result the fans would largely fill in the blanks themselves for the "character" on the screen. Realistically Mario, Link & Samus were me as I largely grafted my own personality to them when I first played the older games.
Whatever Samus Sakamoto had in his head was always going to risk being inferior to the one in the fans' heads. A character like Boba Fett is cool precisely because of how little is revealed to the audience. The audience just sees some superficially cool elements and then fills in the gaps. The WORST thing to do when introducing a mysterious character like that is to fill in the gaps because it is so hard to meet expectations. That's pretty much the biggest problem with the Star Wars prequels. Every fan had just spent 20 years filling in the gaps themselves about the Clone Wars and Anakin's turn to the Dark Side. So then George Lucas told everyone the official story and it didn't measure up and backlash ensued. Metroid is the same thing. Sakamoto's vision of Samus does not measure up to that of the fans.
I'm not saying that we should have one dimensional heroes but I think it would work better if new IP was used for that. Olimar has a real backstory and no one bitches about it because there was never some glorified player avatar of Olimar that we all got attached to.
Samus being a Chatty Kathy broke the atmosphere of the entire series. Samus doesn't need to be silent and emotionless but she needs to shut the hell up when she's by herself. Only Morgan Freeman can get away with narrating a story these days. Look it up. It's been proven by science. Everyone else, especially Samus, needs to express themselves through actions and let the audience infer how she's feeling or what things mean. Other M was just so heavy handed with everything which is the exact opposite of what made Super Metroid so good. That game told you so little yet you understood so much. Find a new item. Look for a place to use it. Baby Metroid saves Samus. Saved its "mother." In Other M, it's like Sakamoto didn't understand how to use metaphors. As if Baby's Cry, The Baby and Bottle Ship weren't obvious enough, Samus has to explain what each means at least 5 times.
Despite how safe Other M played it gameplay wise, I still liked it. It's leaning in the right direction despite all of the missteps. The series does need to evolve but it's saddled with over 20 years of tradition. I wonder how far anyone can really push the series without breaking something. That said, I'm a fan of reboots. I feel like it can be liberating. However, there's no point if the people in charge don't really commit to it. Would anyone have the courage to start from scratch? Comb the series for the best elements and toss out the rest?
One thing to keep in mind, Other M was Nintendo's first real attempt at a full vocalized, cinematic interpretation of one of their primary franchises, yeah they had vocals in Star Fox 64 but not near the level as this. While I don't think it was great, I actually ENJOYED Other M, and I like how they fleshed out Samus, even if it had some major flaws that could be rectified in a later game, but I still don't like the fact that in this industry feminine traits in characters are frowned upon.
The fact is that when one fleshes out an avatar you are going to upset someone, because they have already imagined what the character was like, but that doesn't mean you forego evolving the character. The fact is that the Metroid series is just not that popular anymore, and the base is shrinking. Not to mention people are getting more and more tired of the "emotionless hero that kills things", that is why I love Mass Effect, you have some exciting, heroic (or evil) characters that have complexity.
Anyway, all of this is meandering why too far from the topic. I think why Reggie dragged his feet is that he really didn't expect to even bring the game to the U.S., but with the major slow down of Wii, he is having to scramble to pull games together to at least maintain some semblance of software sales until Wii U is released.
