Yeah, it's mainly how Samus is depicted that really grates on my nerves. They make her seem like it's her very first mission, when it's supposed to be her penultimate mission (followed by Fusion, after which she retires). But even in Metroid/Zero Mission, she was the strong and silent type, so in order for her depiction to make sense, it would have to have been during her time in the Galactic Federation. And what really irritated me was that Samus had all of her upgrades the whole time, but you had to wait for Adam to authorize them to use them. It's a very stupid way of pacing the game, and they should have done it the standard way and have you find them in the environment. If Samus were depicted correctly, she would have gone, "Screw you, Adam. I'm activating them all right now."
