Yeah and dozens of dozens of those reviews are for the most recent version right? (the verison a user would be playing) not for any updates that came in the last 4 years right?

If people can dislike it for saving them time/validating their opinions why are people clearly not liking the positive reviews for proving that they have good taste in the same amount? clearly more people who like the game are in the review section right?
The same (not recent ratings) goes for 1-3 star ratings and their likes, too.
I don't put much credit in the rating system here at all - tastes differ and this may be more important than the perceived quality of a major rating, as you say many ratings are outdated and may or may not have changed for the people giving them, people rate games for things they are not attempting to be or other stuff that they shouldn't rate it for like update frequency (not only my opinion but site rules say this shouldn't happen), and so forth. Thus unlike another poster I actually read ratings - some better ones, some worse ones, as long as they deliver detailed aspects and coherent arguments past "everything is great" or "everything sucks" to see how this would apply to me.
So we are in agreement that the plain average score cannot be the one to end all metric. However, some random derivation of them, not even properly executed I would guess, cannot be any better than the original data. Or did you comb through all ratings, added the absolute amount of likes for all 1, 2, 3, 4, 5 star ratings, calculated an average, corrected for people only liking 1 or 5 star ratings regardless of arguments? You compared it to the data from other games with similar ratings to ensure it isn't just a general thing of the review section? My guess is, and apologies if I am wrong: Nope, you are trying to apply some pseudo-mathematic gut rating to justify your position on this game as "middle of the road" - which it may be for you, no doubt about it, no problem with that - without even giving a proper reasoning by objective facts about the game itself which would make it worse than 5 stars.
In the end, ratings are an expression of taste. When I like a game, I like it, no matter what others think, and vice versa. There are some objectively bad things that can happen - bugs, missing renders - but that's it. There is no real way to say "this is objectively not a good but a middling game" whatsoever, and your method about "likes of ratings" certainly isn't in any way applicable to even remotely show popularity or lack thereof.
