Survival horror fans are generally not too interested in gameplay value. RE4 was a revolutionary game from a well established series and it came out in the perfect period. It checked all boxes but it was easy to get into for the general audience (adaptive difficulty, nice cutscenes and pretty graphics). MGS3 is a similar case, one of the greatest titles ever that was also appreciated by the mainstream. To speak the truth these games were loved by everyone for the wrong or secondary reasons and only a small community was aware of their mechanics. This seems a bit elitist but I don't think it's too far off the reality.
Game design is not considered when people talk about their favourite games and often also in "professional" articles. "It feels good to play", "it has a good story", "every attack has weight behind it", these are only some of the recurrent phrases you can read in every forum.
When you see people demanding a remake of MGS or RE4 then you can be sure that they didn't get their meaning gameplay-wise. All of their requests of changes are absurd, can break the balance or follow modern trends which would only create a detriment to the original masterpiece.
Back to TEW, it is considered a survival horror. Willing or unwilling, it is compared to works like Amnesia, Outlast or other popular horror games and part of its buyers doesn't want action. So when you have to shoot a lot of enemies then they are frustrated and they even say that the gameplay is mindless. You can see the same attitude among certain groups of JRPG fans who think that genre is deeper than something like GoW or Ninja Gaiden.
TEW is a great game all around, like I said, but people now is more attracted by the "realism" of RDR2 or TLOU2. They want cinematic games with the highest grade of visual fidelity and easy to discern mechanics. At launch TEW didn't have the same technological effect as RE4, it didn't have a popular series that could push it, and Mikami's name wasn't enough for the mass.
God Hand was more unlucky than The Evil Within. Low budget 3D beat 'em up with nothing else than combat. Ok, I love the wacky humor and its simple theme and music, but everyone plays GH for the combat. In online discussions GH is treated a bit better because 1)it has vocal fans, 2)it's an action game so it's harder to find people who despise the action component, 3)people like to trash talk IGN even if they didn't play GH (like the IGN reviewer).
The only thing a competent player can do is spread common sense if he wants to. Speed runners can be helpful,
@Infinity_Divide has done great videos full of knowledge and passion in a challenge run context, sites like Stinger can analyze and overcome misinformation and inaccuracies. Dedicated communities are too small to change sales numbers but they can sometimes contribute to increase a game's recognition.
