I realize this isn't a "new" post/topic but it's been discussed so much over the years. 3 key points:
1. People's idea of food quality is extremely subjective to each and every individual single individual. (Hope that narrows it down enough) Taste, texture, presentation, serving size, cost, nutritional value, fit in one's diet, allergies, ingredients, smell, blah blah blah to name a few.
2. Mass prepared theme park food that is simultaneously available at dozens of places at the same time probably should alert the eater that they aren't getting individually prepared gourmet breakfast food with a pinch of this and splash of that. Further, comparing said food to McDonald's (drop in fryer food and the like) indicates a probably less than fully rounded eater with the sophisticated pallet requiring a rinse between courses.
3. Cost - For some people (I live in the NY/NJ area) the cost of most meals at WDW are very reasonable. I pay a whole lot more at home than I do there. I do never choose to experience dining experiences with or without characters. I fail to see the point in having my meal with characters or paying to have a scenic view, etc. (I have done meals to get better seating but that was very intentional and certainly NOT for the food).
I am food challenged and can't eat very much at any one time. I can exist on an order of crispy bacon for breakfast, an order of potato tots for lunch and dinner and then nibble on a main dish in the evening (mentioning this because my take on food is different).
