The real magic of Disneyland's Fantasmic! is that it takes place on the Rivers of America, using the two big boats that many visitors rode and/or saw earlier in the day. And then the whole thing is transformed into this jaw-dropping spectacle. And on a gorgeously cool SoCal summer evening, or a crisp Christmastime night, it's just electric. It could only happen at Disneyland.
I've seen Fantasmic! at WDW several times, and it's all rather sad because of the cheaper sets and stagecraft they use there. But then it's also in this cheesy Shamu Stadium thing that can only look like
Theme Park Water Show Facility that is sealed off from the park until showtime and lacks any sense of magic or drama or mystery.
Welcome to
Shamu Nights!... er,
Fantasmic!
I get why they did it that way, but it just falls so flat and kills the special vibe of Disneyland's show. That the WDW management there lets the show's physical plant rot for decades hasn't helped. Disneyland's version has had three big rehabs just in the last decade with major stagecraft improvements, while WDW's is still stuck in 1998.
I've also seen Fantasmic! at Tokyo DisneySea. Being Tokyo it's a triumph of technology and impressive visuals. And the DisneySea lagoon is a big improvement over WDW's Shamu Stadium. But at Tokyo it's all so big, and so distant from the audience, that it loses something. It's impressive, but it lacks heart. (It doesn't help that the dialogue is in Japanese, but the scale is just too massive to connect.)
If you squint you might be able to spot a Princess. And maybe Mickey.
Disneyland USA truly has the best Fantasmic!, and this 2.0 version should ensure it stays that way.
