Haha, wow, I can't believe all the food snobbery on this forum. Of course Domino's isn't made perfectly, from the highest quality ingredients, but what do you expect for the price? It's perfectly palatable, and anyone who says it tastes like cardboard is a pretentious [censored]. I still prefer Papa John's, just because of one specific pizza I really like.
I totally agree with you regarding the way everything must "svck" or "rule" on most forums and that the lack of objectivity gets tiresome. However, people have strong opinions about food in general. People's palettes, what they have available in their area, what they're used to, their tolerance for certain ingredients, etc. all play a role, and there's no way to tell if they're exaggerating or not. I'll eat most kinds of pizza if I'm hungry enough, but given a choice I would not choose any of the large pizza chains over a decent pizzeria. Part of that, like I said, has to do with the fact that I have a low tolerance for preservatives and sodium, which pizza chain food is usually full of.

Papa John's "regular" (as in non-specialty) pizza, for example, isn't worth all the sodium and calories to me.
