At this point, I've realized that people will complain about this show regardless of how amazing it is just because it wasn't created some time before the year 2000 so negative reactions don't even phase me anymore. The show looks great so far and it's very nice to see projection images back over the lagoon. It is also lovely that fountains will be used more in the show!
And as far as theming, it looks like it'll be exactly what I thought it'd be. Illuminations 2.0 (or is this like 3/4.0 now?) with IP which I don't mind as long as the IP is used well (which it seems like it's being used in an appropriate fashion so far). Very excited to see this in person in October with my family!
