Paul Pressler (president of Disneyland) introduced the "Light Magic Show Premier Party" to the annual passholder's as the "first public rehearsal"... Everyone was expecting a premier, not a practice run-though. His welcome speech was "up" and there was excited-anticipation in the air...
... and then the parade started...
The new soundtrack, "Dream our Dreams"... is a bit "leprechaun-ish" feeling and not very dynamic which lends itself to uninspired dance choreography. The dancing is very repetitious (as is the music)... the one fun part in the soundtrack is when a very short melody clip from "Baroque Hoe-down" (the retired "Main Street Electrical Parade" theme) is woven into the music.
The show seems to have very few "details" in the way of "off-staging energy" that has been evident in past Disney Park street entertainment shows (The Electric Light Parade, The Lion King Parade, SpectroMagic...). As the floating stages travel the parade route... they "just travel" between Small World and Main Street... very uneventful and unentertaining. The "storyline" is also very vague...
If you're waiting for (or expecting) something exciting such as a "Fantasmic-type of show rolling down Main Street"... this new show is NOT it! And even though "Light Magic" is one of the most technically advanced shows ever produced at a Disney Theme park.... that fact doesn't automatically make it a great show.
If you want to go to Disneyland to enjoy the rides and attractions and the other shows since they are not affected, GO. You'll still enjoy one of the finest theme parks on the planet. If you are planning a special trip to specifically see this new attraction at Disneyland, my suggestion is to wait until the show's refinements have been in place for a while... a "long while"...
[ ed note... this "parade" has been recalled back to the drawing board and was shelved indefiinetly]
