I gotta say I agree about the emo-retarded nature of a lot of Japanese characters over the years, and with how anime-styled this game looks, it would seem to go hand in hand. I'm anticipating flat voice acting making that feel even worse, and with how present the cinematics and backstory will be, I'm preparing for pain throughout the game.
And I don't get the authorization thing; Samus has always been the one, single person in the galaxy to get the job done regardless of the cost when no one else could. I think Echoes made you feel that more than anything. She's a no-holds barred survivalist one-man army that kills EVERYTHING in sight. Having her be managed to the point that she's going to hold back using her full arsenal? There's a disconnect for me about that. Regardless, I do trust them with the gameplay itself because that's what Nintendo has always been, and will always be, exemplary at; it's their top priority. Game-driving plot and story, not so much.
