Why? They have their (old-fashioned) taste, which is fine. If they don't have fun, that's what they should talk about. I much prefer that over reviewers that try really hard to pretend that they are "critics".
As mod More_Badass has already hinted at, first off, they are entirely predictable. There's no excitement or interest from what they say about games because it is always the same. Moreover, they have an agenda. They've already spoken on how they get much more hits when they are negative about popular games, and so they do that more and more, and it's no surprise that something like Uncharted or The Witness or any other high published or talked-about game gets negative comments from them. Three, they are incredible shallow in their criticism. Saying something like The Witness should be a five dollar iPhone game is entirely misguided and misses the entire point of the game (and ironic since that is a mostly mechanical game that they seem to enjoy.... and, tangentially, they don't play enough of games to finish them, but whatever), and their dismissals of Uncharted 4 and Last of Us for only the first small percentages of those games is rushing to pass judgement; it'd be like complaining about 2001: A Space Odyssey because there's nothing but monkeys.
The closed mindedness of them is frustrating and gross as someone who enjoys the medium. I love film, as does my grandma. If I went into every horror movie, since they seem to do well financially, and complained that they are "quiet quiet LOUD quiet" or predisposed myself to remark how terrible they are because it would get me hits on my also-ran youtube channel, I'd miss out on stuff like It Follows, or The Conjuring, or The Exorcist, or The Thing, or whatever. And, to compare them to my grandma, it'd be as if saying film peaked and offered very little from 1940s onward.
So, yeah, it's not that I disagree with their points on Pre-Rec regarding games because I value criticism that challenges me and my thoughts (though I haven't watched a review of theirs in well over a year and only catch streams with Jay on them... Speaking of, I wish Shy would point out when Jay was on a stream when he posts in this thread), I'd be fine. But it is the fact that they are closed minded, shallow, ignorant, and doing some of it for "the clicks" that I'm confident when I call it "predictable trash," and that it bothers me that people, because of the RLM connection, seem to reinforce their silly ideas on what games should and shouldn't be in such narrow and trivial ways. I think one of the best things they criticized was The Order because they got to use their film backgrounds on a mostly cinematic game that failed in every conceivable way to be cinematic (even if Jack screws up his film terminology in that review, and they don't go that far into the basics of filmmaking to explain why that game fails).
Maybe video games are a crap medium since it brings out the pettiness and superficiality in people... like comic book movies. Maybe it is that people online who are young and/or don't read actual criticism don't understand it. I don't know.
And, that's probably my last words on Pre-Rec other than asking if Jay is on a stream. Sorry.
