We are only thinking of malls in the classic context.
For the last 10+ years many "malls" have been outdoor "areas" with shops, beautified walking paths, communal spaces, grocery stores, movie theaters, etc. Essentially miniature downtowns.
We have both these and the classic style mall here. Only 2 or 3 classic malls any more. However, they are all VERY successful. There were 7-8 and I've watched many die, or be taken over by distribution hubs, data centers (think big non-customer facing building)
We've had about 3-4 outdoor malls developed in the last 10 years. All are going strong, albeit they are new.
