I often avoid things while they're fads; even when its a case of genuine Quality. The experiences people are able to turn into fads like that are likely to be available later, after the noise has faded, when the tribal implications of the thing are no longer so severe.
"Firefly" was great. I didn't need to subscribe to a TV service to experience it "new"; I just waited until a DVD set showed up cheap. I don't think I lost anything by failing to join in the tribal, emotional dramas that surrounded it.
Or to put it another way, not seeing what other people see in X is probably a failure of your vision.
On the other hand, "if it's popular it's crap" is useful as a tribal identifier. Arbitrary standards of judgement always are.
Good luck.
