I don't think it's stretching it, everyone is different, I'd rate the story a 6, the game an 8 and overall I'd say a solid 7 but with asterisk stating that it ruins established characters. 5 is mediocre on my scale, 6 is decent, 7 is solid/good, 8 is great, 9 is stellar & addictive, 10 is when the stars align and make a game that is all a 9 is but also has very little problems and is finely crafted. This is not a 10, it's not a 9 either and at times I want to drop the story to less than a 5, a 4 maybe (poor) but somehow it manages to stil rise above it despite all the problems and writibg issues, somehow ot manages to be decent enough with the shear magnitude of production, VA and the brutality of it among other things. There are times I wanted to drip the gamepkay to a 5 like this...
... yeah, it gets even worse than that at times like whole monster boxes just desending on you and you can run left and right or in a circle and regain stealth to takr them out or just pop them if you feel like wasting ammo or even worse, have them all come at you and beat them with a melee weapon, they drop a melee weapon and you pick it up to kill the next guy who drops a melee weapon and so on. I was playing on hard with companions on survivor and materials on moderate and the majority of my deaths were one hit kills, a boss, a stupid just scare where enemies are attached to walls and grab you or taking an arrow in the open. Still, the game despite all it's issues manages to push past all that and rise to being great, I can't explain how so besides it being so well crafted, the level design being great at times and the core gameplay and feel being, well, great
Idk, a 7 for me and I wouldn't even question someone with a 5 or a 4 because I can see why. I don't question peoples 8s or 9s either but 10's, nah, there are glaring issues you can't ignore and I can't believe anyone would rate this a 10, as long as they aren't a kid, a teen or a massive casual who cosumes very little media. You'd have to ignore so many problems, your rating of 10 becomes a joke like the 1s, 2s and 3's.
I've seen people put up videos on Sekiro showing similar stuff where enemies just don't react. It happens in all stealth games every once in a while. Also, I'm not sure what difficulty level Jim was playing on. Could have been easy mode for all I know.
Your weird choice of difficulty settings probably isn't the best way to play the game. Putting materials on moderate for example is going to cause stuff to rain down on you so much that it ruins the survival horror aspect of the game. I don't see how you died to jump scares, unless you never topped off your HP bar.
My scale goes from a 6 to a 10, for the most part. If I ever actually rated a game a 5/10, it would have to be one of the worst games I ever played. I'm about a quarter of the way through my second playthrough. Overall I think I'd give it an 8.5 now. The Jackson parts are way too slow the second time around. I don't like the scavenger hunt collectibles aspect of the Trophies. I don't like how the game has sections where you are locked in, and can't go back. Like when you cross a certain section with your horse, and a cutscene initiates, and there's no going back to the area you were exploring. You're now locked into going forward. I hate that, because it's do disruptive to gameplay. Opening cuboards and drawers takes too long too.
Since you rate on a 1-10 scale, and I rate on a 6-10 scale, I think we are more in agreement, than disagreement. Since a 5/10 is average/mediocre for you, converted to my scale average/mediocre would be a 7/10. Likewise, your 7/10 score would translate a little higher on my scoring scale.
