It's honestly what it boils down to. A series can have good writing or art and whatever, but if you don't like it then you just don't like it. Same with the opposite of it.
I love Fallout New Vegas, but god damn is that game a piece of shit in many ways. Still, a 10/10 for me while something like Witcher 3 which is critically acclaimed is meh for me.
It honestly annoys me that people don't understand this simple concept lol
