Saw around 10 minutes of the video, dude is focusing WAY too much in things that last like 15 minutes total in a 40h+ game, like carrying the blue crystal or the boy/boar.
It seems pretty clear that the game is not for him but he insists in complaining about every single thing. It's not like what he's saying is wrong, but I also can't see it as a problem, it's really just a matter os personal taste. Why bother wasting so much time in a game that he clearly doesn't like? Just move on lol
He explained that outright in the beginning. People were basically hounding him over his old video saying "Haha, see, what do you think now that the critics are all raving about this game?!", which makes him feel he has to reply or else it's gonna hang over him. Like, he says this all as the introduction to the whole video.
You can argue that GoW is a really well done cinematic game and many aspects of his critique can be waved away as genre conventions, but I feel he hits the nail on the head in terms of problems with the combat system, which I don't think is something that can fall under that blanket of protection. I think that you want the combat system to be as deep as you can make it, and they prioritized making it into a stat based thing, while hindering your movement, and then designing encounters that exploit that lack of movement, which are then compensated with less engaging mechanics like the triangle warning system.
Personally, I don't mind these sorts of combat systems myself, and while I don't think it's particularly great, I don't mind the lack of depth like he does...but I think he is providing a lot of good insight to the weaknesses of the game. Insight hte devs might take and improve upon in the next game. I think it's good to have a diversity of voices critiquing the game. So why is he even reviewing a game he doesn't like? Because clearly people wanted to hear his opinion on it, and even though I forgot about him until this review came out, I think it's better that he did review it than that he didn't.
