Probably would have fared better as a movie
The story is a direct continuation of Super Metroid, as it starts depicting Samus' battle with Mother Brain. Afterwards, she is flying through space and suddenly receives a distress call codenamed "Baby's Cry", which as Samus herself suggests that it is named so as to attract attention (cuz apparently a distress call isn't an issue unless someone dropped their bottle) XD.
On the "Bottle Ship", you undergo a short tutorial on how to play. The main thing people are probably concerned about right here is switching from third-person to first-person. It is tolerable, to say the least; maybe not a good idea but it shouldn't affect your experience too much (although you do stand still and can't shoot missiles except in first-person). Everything else is simple; there's an auto-targeting system and as long as you're facing the general direction of your target, you'll be fine.
Now things start to get sour; giving a Samus a voice was a risky venture indeed, which makes it that much more painful to explain that it pretty much failed. Samus has an annoying tendency to state obvious facts during her sometimes exhaustively long monologues, and her voice actor doesn't emote very much, as she mostly sounds like she actually is reading off a piece of paper. Surprisingly, she actually does sound convincing during combat.
Another thing that may irk you is Adam. Adam is Samus' superior officer, and as I've been told, there have been a few Metroid games that gave you all your powers but then took them away from you; the way it's done here is downright insulting. Like a good little puppy dog, Samus won't use any of her apparently already acquired abilities unless Adam says so. That probably wouldn't have been half as bad if not for a particular level where you're literally dying because "Adam" didn't "Authorize" your protective suit (so.....apparently Adam's orders are of a higher priority than my life....). Not to mention, wasn't one of Samus' key aspects was that she was independent?
Besides that, the bosses are pretty fun (one in particular, you'll know what I'm talking about). Regrettably, I can't say much more on why it's good; the gameplay is passable and at the very least you get to know Samus a little better (take that however you like).
Overall, the game feels way too cinematic, and some of the cutscenes are LONG (and they're unskipabble, yay!) like the developers forgot they were making a game and not an interactive storybook. Also, there's an aspect to the story that COULD'VE been interesting, but it's not even resolved in the main part of the game (there's a special extra you can do after you beat the game). The throwbacks are nice, boss battles fun, but in my opinion, Samus (and possibly every Nintendo character by extension) is way better off without a voice.
Rent it first, or try to get it for cheap. I don't think even Metroid fans will be able to tolerate this.
