I could not *stand* Morrowind.
I don't think I would ever enjoy it.
I liked Oblivion for like...2 months.
And then I realized it was a very dumbed-down, uncreative, hand-holding RPG experience: Every non-storyline quest basically involved going into a dungeon and killing someone, or going into a dungeon to find the lamp of metrosexuality or some such.
I guess after playing Arena and Daggerfall I had high expectation for MW and OB and was let down by both.
The only reason I played Oblivion for as long as I did was because I used several mods, usually the "overhaul" ones that changed almost everything.
