I think Special Spice is a good song, it just can't compete with something as legendary as Zip-A-Dee-Doo-Dah.
The real issue with the ride is the story, lack of tension and monotonous positivity throughout the ride. If they reworked the entire Dig A Little Deeper/Lift hill segment to be thrilling — possibly adding Dr. Facillier as the villain of the ride — it would go a long way in redeeming the attraction.
I'm just hopeful that the faster pace of the Disneyland logs will make the ride's stupid story feel less obvious, as park guests will be zipping by too fast to think about how ridiculous the quest for a band of critters is.
