I can see the criticisms and Alduin is a pretty weak villain overall but I still think a lot of the lore in Skyrim is pretty cool, especially the stuff with Miraak, the Dragon Priests, the Falmer and the Dwemer. Skyrim is one of those games where the best parts are the side quests and the DLC. Alduin’s story is pretty meh in comparison, though I do really love everything with Parthanaax and the Greybeards. I also really love the foreshadowing with the Thalmor, which hopefully will carry on into ES6, because they seem to have set them up to be the major villains in the next go around. Especially if you buy into that tower theory that some of the lore nerds have (potentially) uncovered.
