Definitely. Skyrim has "It". I can't define what "It" is, but Fallout 3/New Vegas had "It" as well. Even Shivering Isles had "It" to some degree. Morrowind is the epitome of "It". Oblivion did not have "It", not even close.
Verisimilitude is the best word I can use to describe it, in some ways Skyrim is even better at it than Morrowind.
But yes, there appears to be two kinds of dungeons in Skyrim: Quest related dungeons and Radient Story dungeons which are not linked to a specific quest but despite this they aren't just random and generic like 90% of the forts/ruins/caves were in Oblivion. Every dungeon I've encountered has had something unique going on (just like in Morrowind).
I'm pretty pleased with Skyrim so far, and this is from someone with a love/hate relationship with Morrowind/Oblivion (loved Morrowind, hated Oblivion)
