There are certainly other issues with the game, things that will cause you to yell in fury, things like Samus' utter instance on running into so many rooms. Doesn't she know by now that when she runs into a room the door is going to close and lock behind her? Apparently not, because she does so repeatedly, the doors lock repeatedly, and there will almost always be some creature who emerges from behind a wall or the ceiling or the floor to try to pound her to smithereens. If she would only proceed with a modicum of caution through doorways she could save everyone so much trouble.
However, the game overcomes all the above deficits and issues by creating a new Metroid title that feels like both an homage and something new and wonderful. If you transported that little kid from 1986 who just had his mind blown learning that Samus was a woman to 2010 and sat him down in front of Other M, the game would be utterly recognizable and he would be able to progress smoothly in it. Yet, it is a title that takes full advantage of the Wii's motion-sensing controller without making it feel like a gimmick.
Metroid: Other M features tons of power-ups, oodles of hidden items, and more enemies than you can shake a power bomb at. It has a great story, good production values (this marks the first time Samus has been given a voice), and good graphics and sound. It may not be perfect, but it does prove that even if she's a girl, Samus Aran can hang with the big boys.
Metroid: Other M is rated T (Teen) by the ESRB for Animated Blood, Violence.
