OK, I think those who live in Southern California are lucky, and have had amazing unique pre-planned malls for decades. (Not counting the areas that have morphed from downtown to cute unique shopping areas, or beach communities). Most of these malls/areas are outdoors, due to the weather being so nice)
In San Diego, I can think of Horton Plaza was one of those that started a truly unique one of a kind mall.
The Viejas Outlet Center is beautiful, has special evening shows in their showcourt.

Fashion Valley Mall has morphed into a very unique upscale mall, and then you have nearby Mission Valley Mall and Hazard Center, plus shops and restaurants that built next to the big malls. Connected to each other using the San Diego Trolley rail system.
Fashion Island in Newport Beach has a unique history, using the site that hosted the Boy Scout Jamboree and has amazing views, and great common areas (I love the Koi Pond). Every Christmas Season, the mall is well known for its Christmas Tree, in fact, a 30 minute TV is offered when they light the tree, Disney works with them (and nearby Irvine Spectrum, which is owned by the same landlords) in producing the special and offering Holiday Entertainment.
The Grove in the LA area is amazing, fairly new, but built next to the famous Farmer's Market (and run by the same management) near the CBS Television City Studios complex.
This heavily Themed Mall shows what a Shoppertainment Mall should be, a great free Trolley that was designed to run on electricity without a hanging system, uses the same charging system that Disney uses to power the Subs in Tomorrowland. This mall opened the same time as DtD, and has grown and seen great attendance and has special Christmas shows and a large tree, they also get a 30 minute TV show of its Christmas Tree lighting.

So there are some of the malls I think to as a "destination" mall, all much better than DtD, offering better entertainment, restaurants and shopping.
Heck, Universal CityWalk is also a great run mall, that does get quite a bit of their business from locals. You have things like the iFly sky diving experience, and the 5 towers entertainment stage area next to the theaters with its very large Video wall. This area is used quite a bit in filming things for TV shows and features major bands (i remember seeing Smash Mouth and meeting the band there years ago).
Now, I personally wouldn't drive there just for the mall nowadays due to traffic and parking hassles, but I do spend time there most of the time after visiting USH.
But there are a lot of great malls in Southern California, and I know I am missing some other good choices, but this is the bar that Disney has to compete to get locals to visit, and it truly looks like Disney has decided to not go after locals for DtD, and focus more on the current Hotel guests on property, and at nearby off-property lodging. Which isn't a bad strategy. It will never be the money maker the parks and Hotels are currently, but if can at least pay for itself, then Disney gets a good amenity for its guests. I remember the original shopping complex at the Disneyland Hotel before the Resort conversion, a nice set of shops, with a focus on the Hotel Guests wants and needs, and that is what we are back to.
Slightly off-topic, but I do miss the old Disneyland Hotel Fantasy Waters show. (Free and open to the public)
