Getting back to the OP's point (yeah, I know, good luck with that) I think it depends on the deftness of the brewer. I really like Sam Adam's Summer Ale, with the grains of paradise. I am a Pumpkin Ale lover, but again, only those with subtle spicing. And I adore Christmas ales.
I think in general, people are trying to do something "new" more than something "good." And they're overdoing it. Left hand Fade to Black is a great example, what makes it amazing is the balance of malt, hops, peppers, you can detect each note. I've had other pepper beers that just blew away my palate, not enjoyable.
Of course, you can make the same argument about IPAs, with more time and exposure, I am finding I enjoy those with malt / hop balance rather than drinking hop juice.
Funny, I was drinking my Maibock last night, thinking, damn, simple beer, simple hops, yet balanced, delicious, and drinkable. Maybe too many beers are "unique" but not drinkable.
Anyhow, there's room for everyone in our tent.
