A few random and vaguely connected thoughts:
I wonder if part of the problem is that we're all talking past each other on what the word "journalism" even means. It's one of those arguments over definition [http://slatestarcodex.com/2014/11/04/ethnic-tension-and-meaningless-arguments/] that goes in circles[footnote]Of course, there's also the whole "Many people are just twisting the term to mean whatever they currently want it to mean to justify their own bullying and harassment of others, so it's a waste of time trying to argue the meaning with them" thing.[/footnote].
I'm not sure the traditional definitions of "journalism" can even really apply to the field of covering artistic mediums (other than the inevitable low-hanging fruit of behind-the-scenes tabloid gossip). Even "consumer reporting" seems a bit dry, since the very purpose of the products being reviewed is so subjective. Maybe the solution is to just stop pretending that it's an industry in which objectivity can be applied?
The rise of YouTube has supplanted traditional reviews for a lot of people, but the thing about "broad appeal" is that a number of the people who flock there don't take part in that sector of games media, they barely even know that YouTube playthroughs and indie gimmicky reviewers exist. And then there are people who just prefer text reviews, for completely arbitrary aesthetic reasons. Of course, one fun feature of capitalism is that, if not enough other people like the same things you like, you are forced to either change your tastes or do a whole lot of extra legwork, so text reviews are slowly fading out in these big high-profile aggregators and being relegated to niche blogs and that most dreaded of website features: reader-submitted columns.
I do think it's ridiculous that "games journalism" gets blamed for that Metacritic thing, rather than the rich assholes who hold the spectre of Metacritic over their serfs as an excuse to not be held accountable for their actions (but, as we all know, the people who claim to be angry about media corruption will always do everything in their power to allow the people screwing them to continue screwing them as freely and easily as possible, while tossing safer targets to the dogs).
