One thing I hate about old games like this getting perfect graphics and voice-acting is that it leaves less and less to the imagination. With the original Metroid (and Mario, Zelda, etc.) they were all 8-bit and pixelated so you couldn't have enough detail to handle detailed facial characteristics like eyes, noses, cheek-bones, ears, hair, moles, etc. It was jsut some blocky pixelated distortion that could have been a super-model or a hideous freak, but you couldn't tell because of the blur of pixelation. Sure, you saw Samus semi-nude at the end of the games which let you know she was actually a woman, but that was pixelated like I'm pointing out, and there was of course no voice-acting so you didn't know how she sounded.
So my gripe today is the high-rez graphics and all that leave far less to the imagination, and to me that kinda sucks because there is some appeal in not knowing. Samus' blue spandex form-fitting suit is so revealing that she almost might as well be completely nude, because you can see perfectly how her body is shaped. Inside the suit you just couldn't tell if she looked like that, or if she was some butch female space marine, or whatever.
There was a time when Samus' seemed to have a different hair-color with each game, and now its just boiled down to a predictable and overdone blond color. Princess Peach, Zelda, etc. are all also blondes. Why couldn't Samus have had another color, like red for a change? In fact, since she is an alien, she could have had green hair or something. Why did Nintendo make her into just another Barbie clone? We have too many barbie clones in the world as it is!
One of the last remaining mysteries was her voice, and it seems now we're losing that as well...
