I just wrote a brief review of Metroid: Other M and gave it 3 out of 5 stars. Yes, I'm going to fall into that camp.
I just didn't think the controls ever worked the way they should, or that the game itself was well thought out. Other M should be the poster child of Nintendo's asinine policy of crippling their games just so some mythical expanded audience can play them. Either you make complicated games with a suitable control scheme, or you stick with porting out ancient Super Mario Bros gameplay (and even then I didn't think those controls were any good... shaking is terrible and the B button is ignored.)
Stop trying to do both, Nintendo. Other M needed the Nunchuk, end of story.
It has become apparent that Metroid exists solely to fill a perceived gap in the Wii lineup: serious space marine alien shooter. As long as there's a Metroid in production, Nintendo can point to those mediocre sales and say "See, we ARE giving hardcore gamers what they want." And as a ridealong, here's a new, unasked-for Sin & Punishment.
And yet, the Prime series - even the Wii-specific #3 - are better than Other M at every turn. Interestingly, when the first Metroid Prime was released, it was snubbed by the hardcore because of the unique take on FPS controls. I imagine those people have even less nice to say about Other M's controls.
The game isn't unplayable. I beat it in about ten hours (short!) But every step of the way, I felt that the game was designed around gimped controls, and never that the simplified controls were making the game easier or accessible or more fun. You can't shoot missiles unless you throw it into first-person. You can't change weapons, rather, this time every new weapon type is simply a barely-noticeable upgrade to your basic beam cannon. The distinction between your beam and your missile (when in first-person) is based entirely on whether you're locked on or not. And the transition between horizontal Remote to pointing Remote is clunky.
Much hay was made about the first-person mode being a chance to explore your environment and uncover items that the 2D view would not necessarily show... except that all the items are marked on your map anyway, so it's hardly much of a treasure hunt.
And why does the game have to remind me what a missile pod is Every. Damn. Time. I find one.
I know people are taking the game to task for its script, and yeah, Samus's soliloquies are little more than snippets of bad high school poetry, but it's the gameplay that bugs me. Halfway through, I realized the problem: this is a video game, not an experience. The Prime games were an experience. Just like how it doesn't make sense for the Raccoon City Police Department to be a maze of hallways and art museums, the Bottleship of Other M is a video game level. Not a derelict space station. It is an environment that could only have been traversed by Samus, even before the alien bioweapon creatures went batshit. The researchers working on that ship would have needed Samus's gravity-defying Space Jump just to make it to the cafeteria for breakfast.
And then there's the idiotic old canard that mindless rampaging creatures somehow have the ability to lock you in a room with no escape until they die. We need to put that gaming crutch right on the bonfire alongside the Lives/Continues paradigm.
Nintendo has Kirby and Donkey Kong Country coming up, and both of those will use a horizontal Remote. Now, I wouldn't expect those two franchises to require the depth of control that Metroid needs, so I don't see them being as grisly as Other M. I wonder if either of those games will use the damn B button.
Halfway through, I was ready to give it up. I almost tweeted "Never playing Other M again" half a dozen times. But one feature kept me in the game: the Theater Mode. Beating the game unlocks a special two hour long Metroid Other M movie. Clark and I watched that in its entirety the very next day after I beat the game. Lousy script notwithstanding, the cutscenes are gorgeous. The movie version supplements them with in-game footage and audio, so you end up with a complete feature film. Every game needs to do this. I can think of only two that have, Other M and Metal Gear Solid 3: Snake Eater.
This is not a recommendable Wii game, but keep in mind that 3 out of 5 is mathematically better than average. Although I think I'm trying to talk myself into giving it a 2. It does look great, it's frustrating but not so frustrating that it's impossible, and it does follow up directly on Super Metroid (as if that matters)... but the Metroid Prime Collection is a much better time.
EDIT: I did bump it down to a 2. Upon re-reading my review for publication, I realized that I myself was not even making the case for a 3. Too much bad, not enough good.
