We could argue for years and years (as we already have) on if this was worth it for Disney, if it will be deemed a success, how well it will sell merch, etc, etc, etc...
Doing so is simply going around in circles imo at this point though. Once the land opens, we should judge it based on how good the attractions are, how immersive the land is, how good the land entertainment is, if the quality of the merch/F&B is up to snuff. And comparisons to Potter and Carsland in this process are obvious. I think we should also look at how much this improves DAK as a park as well.
Point being, i'm sick of coming in this thread and reading the same conversation for the thousandth time. It either is or isn't worth it, but it's here no less.
