Don't let the StLouis Mall scene become too involved with the Branson situation, St Louis has had its' own issue that Branson does not- urban sprawl.
The point of a shopping mall is for recreational shopping, and with the mass exodus of North St. Louis residents moving to the neighboring counties-St Charles, So. StL, the economy, and the community could no longer support the once bustling anchor stores and malls, so they shut their doors. This has been detrimental to North County, but with the recent addition of the Mills Mall, the area has had an infux of revenue. More and more small shops and storefronts have popped up to serve the market left open after the departure of the malls in the mid 90's (Northland Shopping Center, RiverRoads, NW Plaza). (My parents both worked at River Roads one of the first enclosed "Malls" in the USA, My grandmother at NW Plaza for 20+ yrs- I remember that mall when it was still outside (before the enclosure) before closure, it was the largest mall in MO, 27th largest in the US, it had 9 anchor stores, and over 200 stores (a total of over 1 million square feet
Branson will ALWAYS have the recreational shopper, and it is visitors that feed this market (something North StL. doesn't have). It is just which has a better location, or a better offering of stores, which is bigger, better, etc.
