Well then that is down to a lack of observation on your part about how things are done.
Another pretty feeble shot from you there, GK. You know full well it's never going to be about ignoring those who disagree. It's just about ignoring those without reason.
It doesn't depend on who wrote the manga. That's again getting into a complete irrelevance. The games can only be compared, reasonably, to the other games- both on the grounds of the amount of people who have read the manga (an irrelevant, tiny amount) and the fact that games exist in their own continuity irrelevant of any side fiction and the expectations created by the games themselves are what we must compare the continuity of plot and characters to.
Samus does not act in Other M as she does in the other games- an out and out fact. To deny that is blindness. That she might act closer to the manga is irrelevance, and as some reviewers have commented- if you are so hardcore as to have read the manga, then you are going to like everything about any Metroid game no matter what in any case.
If they wanted to show a vulnerable Samus who freezes up against bad guys, a prequel was the place to do it. By the time of Other M, it is simply ridiculous. As for Samus' continual blather throughout the game, that's not exactly a continuity issue, but it's still bloody annoying and the idea she might have always been like that in the other games is almost heartbreaking. Maybe if they'd had some better scriptwriters; lines like 'confession time' are apt to make good people vomit.
All in all, a lot of people are just having to be very defensive about the fact that this game has not been as well received as was hoped. This is in turn because... it's simply not as good.
