When I was growing up in the 90's, a trip to the mall in Savannah, Georgia was a premier weekend experience. There was an arcade, a video game store, toy store, a comics and trading card shop, a music store, a theater, a carousel, and a food court with free samples of Chinese food on toothpicks. It was littered with booths selling hot pretzels and cookies. It was a destination in and of itself, the center of gravity for the medium-sized city. People were there for more than shopping, it was the place to be with family, friends, or to take a date. The annual 'back to school' trip there was always the best. For someone from a small town with only a Big K-Mart (no Wal-Mart yet), it was an enviable experience that only happened a few times a year.
So yeah, I'm always biased towards malls. They should exist, they should be awesome. Even if for most cities they're artifacts out of time, effort should be made to keep them.
About three years ago, I think, I went back to the Savannah mall right before Christmas on a Saturday, and I didn't know it had failed and was closing in a few weeks. There was maybe two stores remaining and one place left to eat at the food court. The lights inside were dimmed to maybe 1/3rd of normal. I was the only person there, taking pictures, and it felt like trespassing. It was a sad experience walking through it for the last time.
