The problem is, if you aren't going to put any effort into learning who out there is good to pay attention to or trust, then what's the point of media outlets putting out the effort to give the right games to the right people? Obviously a perfect world would be every site having every game reviewed by people qualified to review them, but that isn't always going to happen, yet there are people legitimately trying to give good coverage of niche and/or Japanese games outside of the super enthusiast sites.
With how hard it is at times to get higher-ups to care about giving coverage to the smaller games, those site that do really need the support.
There's so much nuance when you start to flip over rocks. If you give a shmup game to a standard person they'll review it poorly because it's either too hard (lots of fail) or too easy (they credit fed it in 30 minutes). If you have a typical fan of the genre, they will probably praise it as they are starved for such content. If you give it to a technical player that can 1cc such games, they might just shred it because of a lot of faults most players won't notice. Inaccurate slowdown, too much boss milking, not enough boss milking, some scoring flaw that can be exploited..
There really isn't any perfect solution.
