I tried to get into it a number of times, and the three major things that always wear me down are, first and foremost:

The obscene lack of difficulty in overworld content (next to running completely gearless or taking on group content/bosses solo to create an artificial sense of risk or danger). Most enemies are so easy that you never need to maneuver or use your full array of combat abilities. You end up mashing the same two or three hot keys on every single enemy while your HP remains at 99%.

The weird choice of classes and themes that do not accurately reflect what The Elder Scrolls has always been about. Rather than building classes based on my preferred weapon class, skill sets (Sneak, Lockpick, etc.), and magic classes (Alteration, Restoration, etc.), I have to be locked into a holy javelin-chucking warrior of light, a lightning-slinging daedric sorcerer, a fire magic dragon warrior with wings and spikes growing from my back, or some other weirdly themed class that didn't need to be a core archetype in the Second Era. Like, fuck man.. Base classes could have easily been born under the Warrior, Mage, Thief, etc. and then built upon from there.

The absolute clusterfuck of major/DLC quests that start the moment you walk into town or pass an NPC. It feels like navigating a fever dream as a new player, and it's overwhelming. A thousand tangled threads and no room to breathe. Even the main quest no longer has level requirements at each stage, so the Prophet will bid you goodbye and immediately call out again the moment you leave the cave. It's an absolute mess.

I could go on, but these are the worst three.
