Games are supposed to be fun, but they’re not supposed to be fun for everyone.
So, some people will not enjoy dark souls, because the main gameplay - learning movesets until you’re able to not die to them - is not fun for some people. On the other hand, learning movesets at a really slow pace because the run back to the boss takes ages, or a boss that you can learn quite well but takes ages to kill because it leaves very few openings, or a boss that you would be able to learn except it’s in a tiny arena and the camera always fucks up… these are all areas in which dark souls games sometimes let down players who are geared to enjoy them.
