My main complaint about malls is how _loud_ they are: visually and auditory-ly (someone please tell me what the right word is). Malls are crowded, adorned in bright, garish colors, filled with stale food court food smells. There is very little seating other than at food courts, water fountains are hidden far away in some corner, loud music plays almost all the time, or it's noisy because of all the people. In sunny Silicon Valley, parking is a nightmare but there'll only be one bike stand hidden in a 50 acre space. It somehow has all of the worst features of a busy bazaar with almost none of the good (local products, "authentic"-ness, ability to haggle etc). Just standing in a shopping mall stresses me out.
It's possible that the present state of the art of mall design ticks the boxes for the largest audience possible and I'm the weirdo.
