I don't have a dog in this fight, but fwiw . . .
I have seen several major mixed-use redevelopment projects go through three stages: 1. Initial period of excitement; 2. roughly 3 to 10 years (or even 15 years) into the project, though, they have relatively high vacancies, the public starts to perceive the project as a boondoggle, etc.; 3. slowly and eventually, the project begins to pick up steam again, additional major projects begin to fill in around the big initial project, and before long, the block/district sort of hits critical mass and everyone says it's a true "destination district" and "why don't they build more of these around town?"
Of course, many projects go straight from stage 2 (initial failure) to complete failure. It's just that we should be careful not to draw premature conclusions about the long-term financial prospects because these things tend to take a long time to percolate.
Even if/when they do eventually "take off," it's certainly your prerogative to see them as soulless fake urbanism, etc.
