Shopping malls are interesting because their entire appeal is predicated on a network effect. So when something reverses that effect, whether it's demographic shifts to the area, a large tenant going out of business, or a competing mall, the results can be devastating and you get a vicious circle death spiral. As others have noted, malls in general aren't doing too poorly, but for the ones that are they're awfully conspicuous and downright depressing, so I think those tend to stick out in peoples' minds.
