You're just being contrarian. Please, provide evidence for Morrowind's supposed mediocrity.
The only things Morrowind does well is:
- Being good at something no other game does (open world RPG).
- The setting and lore.
That's quite literally
it. The graphics are awful (compare to Gothic II), the world is dead (compare to Gothic and Gothic II), the music is
extremely repetitive, the sound design is bad too (the Morrowind Acoustic Overhaul shows how the game should sound like), the quests are generic (go there, get me that; very few Morrowind quests are actually different), the faction progression is not bad but ultimately pointless (Gothic made a much better job at making you feel important when advacing through factions), the combat is laughably bad and completely broken (you can spam attacks much faster than enemies can, for one), the dungeons are short, repetitive and few hold anything useful, the writing is bad (NPCs are dispensers of info and don't talk like real people AT ALL, ask them what their occupation is and they give you a job resume instead), among other criticisms...
Morrowind's greatness comes from being a mediocre open world RPG has opposed to a terrible open world RPG (Oblivion, Skyrim, Fallout 3). I love Morrowind, but I would be lying if I said it is "great". If the Gothic games had the scale of Morrowind, I would devote my time to them instead.
EDIT:
An example of bad writing vs serviceable writing:

Commoner - "I am a commoner. I do whatever needs doing -- cooking, cleaning, building, baking, making, breaking. And, by your accent, I can tell YOU are an outlander. Since you're new to these parts, perhaps you'd like me to share a little local lore."

I hunt geckos, mostly. The meat's pretty good and I can always find a buyer for the hides. I also help keep the town clear of radscorpions and coyotes. Not many people live in Goodsprings, so wildlife is always creeping in.
