Riscal Tempranillo

I should be satisfied with this wine, but I'm not. It's perfectly good and fruity and there's nothing wrong with it that I can articulate, but it feels like something is missing, although I can't tell what. I don't like that I'm dissatisfied with a wine that has nothing actually wrong. It seems rather, I don't know, spoiled? ADD? High novelty-seeking? Not something I want to be. Maybe I should just shut up and drink up.
