I was initially going to make a video on this, but I couldn't find the time.  So I'll just keep my thoughts written.   The other reason I am doing this is because Hailinel's complaint on people's complaint.
 
  Let me give you the short hand review of Metroid: Other M, it sucks.  It isn’t that Metroid: Other M is unplayable, your time and money is better spent elsewhere.  It’s a shame because Nintendo has seen better days with Metroid.  To state the greatest criticism, it’s not a real Metroid game despite what the box might say.  The game is best described as a cross between Metal Gear Solid and Ninja Gaiden, both which outclass this game on what it is trying to achieve.

                     The content offered by this game is weak.  The game divided into 4 sectors, the main sector, and sectors 1, 2, and 3, all which take place on a space ship.  The main sector is the laboratory of the ship, while sector 1, 2, and 3 are meant to simulate a forest, lava, and snow zones.  While it sounds generic, that really isn’t the problem.  They have been the staples of the Metroid series.  The problem comes from not being fleshed out.  It gears itself only to serve as a barrier from point A to B while in previous Metroid games, these worlds were the point of interest.  There simply isn’t enough going on to care about it.  They also lack that “organic” feeling that previous Metroid games had.

                    Gameplay takes quite a beating as well.  The game demands a lot of trial and error.  If it wasn’t for that, the game would have no challenge at all.  You meet the same bosses over time, with very little variety at all.  It was as if they had no new ideas to bring to the table.  Every so often, the game stops and forces you into what is called “Search Mode”, which forces you to look for a particular “thing” but you aren’t instructed what this thing you are looking for is.  It is basically a poorly thought up version of “Where Waldo?”  What is even worst, these searches really don’t provide anything meaningful.  At times, the game fails to inform you of important information to complete the game.  It became very obvious to me with the final boss.  The only way to defeat the boss was with a newly acquired weapon, and the game gave you 20 seconds to figure that out, randomly, which would require you to pause the game, go to your list of items and learn about your newly acquired item.  Throughout the game, you have been informed of the skills and items you have unlocked?  Why stop because it is the final boss?  Then the entire game seems to have been built around the Wii remote.  While it certainly works well, the game has a strong sense of being “watered down.”   I’ve played games which supported button mashing, but this takes the cake.  You needed to be somewhat coordinated (eg: Dynasty Warriors, any fighting game), but with Metroid: Other M, it would have been a far more challenging action game if it was a turn based RPG.
 
                   The story itself is utter garbage.  The game is trying to tell a few stories at the same time, and it all collapses together.  The Federation with their conspiracy to keep the project a secret, a creator’s experiment gone wrong, the relationship between the Adam Malchavich and Samus Aran, and Samus’ own past.  No amount of “high quality” CGI can offset this stinker.  It seems to conflict around a lot of the lore and story behind the Metroid series.  Simply put, it is a waste of money that could have been used for improving gameplay and increasing content.

                   Simply put, this game can easily be passed out, even by Metroid fans.  Hell, even if you are a fan of Metroid, you probably want to skip out on this game.  If you really need to get your Metoid hook, I suggest you do one of the following, Buy Metroid Prime Trilogy, The original Metroid, or Super Metroid, and all are playable on your Wii.
