Test Track used to be the attraction i was also not a fan of.
I hated it with a passion...referred to it as *Test Crap*.
NOW however, since the recent refurb/retheme, i am singing a different tune. I like it now.
It is much better themed, and a better fit for EPCOT. Futuristic and fun...with a interactive element to boot. A nice modern additon to the Park, and with no character overlay ( another bonus! ).
Add to that the built in appeal of the Tron-inspired overlays ( yes, i am a Tron geek..)...and ..well, i am a convert now.
*Tron Track* is great !
Other then that, the currant attraction i can think of that i would say is not *worth it * for waiting a long time in line for is the Finding Nemo ride at The Seas. If you have kids, they will likely want to ride....so your mileage may vary.
