Sometimes hype can make you hate something. I used to think Led Zeppelin were overrated, now I think they are a religious experience.
Not much compares for me.
Prince on the other hand....overrated.
Backyard burgers. What do people see in a singed meatball on too-chunky bun.
Fastfood has it right -- a flat burger on a bun that fits. The idea is to get a mouthful of everything -- burger, bun, condiments, lettuce, tomato, etc.... -- in every bite.
They also get fries right. Small fries give you a great ratio of golden, delicious surface to bland starchiness. Those awful big planky fries? Those are for seagulls.
Kidney stone cures or preventatives. Every Freaking One of Them.
As for overrated stuff
Cable News/politics (they're all equally full of it. I think all these bastards work together)
And I agree with everyone in this thread who says Radiohead is overrated. I remember reading an interview where Thom Yorke was talking crap about his fan base when they wanted him to sing a particular song live because he doesn't think they "get it" since the song is so "painful" for him. That is the ultimate example of being a pretentious *****. God forbid your fans, who are the sole reason you are millionaires, want to see you perform a song they enjoy. Before that moment I would probably say they just aren't my style, now its pretty obvious to me that they are being arty and weird for the sake of it. What a load a crap.
Family Guy. Started off funny, but became full of its trendy self. It's given in to nihilism. South Park has an actual pov, but FG has all the cutting edge humor of a seventh grader.
Strangely enough, I find American Dad funny.
