Even though he made some decent points, I still believe that the Prime games had better gameplay (and avoided the problems Bob seems to have with FPS's, along with lock-on), and that it did horrible things to Samus's character (in response to his points about extreme feminism; a woman admiring a man is fine, but being that dependent, especially when you have an established record of badassary, is not). Say what you will about it giving her more traits, it was preferable when she was silent, kinda like how giving Gorden Freeman a Barney (the purple dinosaur, mind) voice would add to his character, but his silent self would still be better.
And while he's right that gameplay-wise, authorization and collection are very similar, in terms of basic in-universe sense waiting for authorization to use the Varia suit is incomprehensibly stupid, adding that much more to the assault on her character.
Of course, right now I'm more worried about the backlash to his "stop being hard on Japan" statements (remember the response to his Halo: Legends review? I don't want that again).
Edit: Since this is an issue I'm pretty big on, I'll blabber on some more:
It's my belief that Other M is an extreme incarnation of a trend that started in Prime 3, namely, a greater focus on linear story and explicit world-building (as opposed to the in-the-background style of Super and the first Prime). While Prime 3 was a good game, it felt the whole way through like it was trying to be Halo to an extent, what with the greater focus on the Federation, dialogue, combat, cutscenes, and generally more upfront story-telling at the cost of atmosphere (my favorite part was when you teleport to an ice section, as it was quieter and reminiscent of the first Prime).
Don't get me wrong, explicit story-telling has its place (MGS3 is one of my favorite games), but it doesn't work for Metroid, a series pretty much made by atmosphere and exploration, both of which were compromised in Prime 3 and done away with in Other M.
