I will be serious and not one of those over eccentric lovers or extremist haters
Flaws I found:
Shooting door shields too closely can cause them not to open and you have to re-shoot and move back and forth a bit until it opens.
Bosses are quite easy but I guess that goes with difficulty but other than those two I find nothing else is wrong and well it's a game that will maybe last long enough for someone to scan everything possible, fill up the log book and find all the one hundred upgrades possible throughout the game.
Upside:
Great addition to the series and giving Dark Samus a powerful role in the whole taking over fellow bounty hunters and making them fight you. Puzzles creating headaches which means those that love to think will feel rewarded because no matter how simple some things are I guess there could be the possible overload and then OH NO what do I do then it's like OHH im an idiot makes well at least ME feel rewarded I don't know about others.
Controls are as good as they can get, maybe room for improvement I wouldn't really know but I find that the controls are easy and not over sensitive or under sensitive and great use of the Wii-mote for turning switches and moving levers makes you feel like you're Samus Aran yourself.
Great new characters as additions for the storyline making some mystery of a whole what are they doing there, oh no they're killing me but I win.
But the stress of scanning to add to the galleries are I guess the only real big downside but everything else will be a breeze for the puzzle game players.
