Reviews are not supposed to be objective. It is impossible for a review to be objective. It's one person's experience with and opinions of whatever they're reviewing. As long as any biases one way or another or are made clear, having personal opinions about weapons, story progression, etc, are completely fine.
I'm not watching the IGN video (either one, actually) and I'm not planning on it, so I can't speak as to whether or not it's a good/professional review, but going solely by the complains you laid out, it's not committing any reviewing crimes.
And who says a game's story can't progress, build up, and twist just because it's the third game in a trilogy? A good saga should have self-contained installments that all stand on their own narrative-wise but add up to a larger, more impactful arc when taken as a whole.
Crusty VGchartz old timer who sporadically returns & posts. Let's debate nebulous shit and expand our perpectives. Or whatever.
