I absolutely loved it.
It's definitely a slower show and relies more on charm and soft humor, but the ending helps balance it with a whallop of epic that reminds me of Illuminations.
The layering of tech is almost jaw-dropping at moments, especially in that spectacular Xmas light sequence with Goofy which is damn near transporative in nature. Both the opening and endings deliver chills packed on top of utilizing what seems to be the height of where they can go with the power of WoC's tech. To say it's impressive is an understatement, I agree that the poignant nature of it seems to reflective of the country's ruptured climate (and man, if Season of Light didn't come in at the right time)... but we need it. Badly.
What I loved most was that the show put the holiday first and synergy second. It's sort-of like a show full of the "So Close" segment from the original, with a central theme allowing itself to numerous shots of various Disney films. And in a stunning, welcome shock, there's little-to-no live action sequences. It's also wonderful that there are a lot of the fab five in the old Disney Xmas cartoons, which feels authentic to the Disneyland Xmas tradition. The bits that do focus around one movie are fitting and never lose sight of Christmas. They provide the comic relief with Feliz Navidad (Three Cabarellos), Mele Kalikimaka (Lilo and Stitch), The Nutcracker (Fantasia, with that one popular acapella group) and Blue Christmas (Inside Out)... they're are also neatly and strategically placed with the other montage segments in-between, with four choices that have not been featured in World of Color's past.
But it all comes around to that powerful ending which is absolutely mind-blowing, throwing synergy to the wind and going for a (mostly) secular, joyous celebration of the season that culminates in a stunning climax. There definitely seems to be a lot of the old Osbourne Lights show in it, giving even WDW fans an incentive to trek to DCA. This is easily the most effective version of World of Color, and I can see it playing for years and years each holiday season. Bravo, Disney.
