I didn't mind the gameplay except for when you had to point the wiimote at the screen, but it wasn't as bad as some people make it up to be, at least imo.
What I really didn't liked about the game was Samus, didn't liked her voice and the stupid "baby metroid this, baby metroid that" shut up! That was so annoying. Just like Link, Samus must have stayed silent, no voice or just text (like Metroid Fusion). And I also think Nintendo put her as a "weak" character, I mean not using her suit powers because Adam doesn't let her is just stupid, they could have found a better way to not make use or her powers.
yeah they didn't want to use the usual lose all your powers thing, the pointing thing wasn't bad for me the change of perséctuve was seamles in my experience, and yes samus was whiny but weak nah, she had issues but she did everything it's not like she was turned into cloud of ff7 just whining all the time
