I'm usually against disney not changing something for a long time, but in this case, spectro was working, and it was working real well, like others have stated, the music gave the park a certain elegance, a somewhat grand feeling, it was classy..
The main complaints I'm hearing on this board about it is the music and I 100% agree, spectro's music tugs at your heart strings, while msep 's music only tugs at the heart strings of the nostalgics, but fails to do so for the newer generations of park visitors. It's soundtrack is stuck in the 70s, its not timeless, its very dated, and the update made it even worse.
Spectro > msep for me, and it sounds like the majority on this board agree... BRING SPECTRO BACK!
