The pattern of "insult popular thing", "ask what's bad about popular thing", "be downvoted to death with no answer" is pretty common. I generally chalk it up to blatant pretension. Everyone wants to feel like they have refined tastes and it's easier to downvote someone than admit you have no legitimate reason to hold a particular opinion.

There was a program on British TV a few years ago where they took some fast food and presented it on a plate as if it had come from a gourmet chef then asked people who don't eat fast food what they thought of it.
Its probably a fair point on behalf of the show but don't forget that the show could have been edited and be full of bias by the producers.
I have come to hate the concept of fast food (although readily admit that I guiltily enjoy various bits like McMuffins and Stuffed Crust) and back myself to be able to tell when something is fast food no matter how it's presented.
I probably wouldn't make good tv for the producer of your aforementioned show.
