One thing is that, like the South Side Works area on East Carson, the new developments tend to have a problem with store fronts, IMO. Store fronts that grow naturally are just riddled with specificity, a unique look, due to vastly different conditions of building, signage, etc. If you look at the signage in the Terminal development, it looks like they adhere to some restrictions on size of sign, sign font, etc., for example. It creates a kind of monotone, and it can even obscure businesses that are there. E.g., in the South Side, the waffle place, or Paint with a Twist (or whatever it's called). These signs/storefronts just don't stand out enough.

I don't know how they could do it otherwise but I bet they could. Have it less finished, and require the businesses to finish the storefront more themselves. Even if it's shoddy, it would look more natural and unique.
