I've managed to partially short-circuit my allergy to hype by telling myself that if I wait until after something is established, I successfully avoided the downsides of hype (buying into something site-unseen that might not even be that good) and intelligently waited for something to come out and get properly evaluated. Also I'm being unique and independent by getting into things well after everyone else.
This has given me a license to come back and check out beloved works whenever I realize I was just being contrarian and stubborn, which is a delight. Also still lets me say "I knew it!" when super popular things become less than beloved in retrospect.
Plus old stuff is often cheaper. It's often a fun adventure to go "Ok, let's see what all the fuss is about," even if it doesn't become an instant new favorite. Example: Twilight, while I wouldn't call it "good", is very funny and very fun to watch, especially if you get a mixed crowd of people that loved it at the time but recognize it's dumb, people that were allergic at the time but have since watched it and can acknowledge the fun, and new watchers.
