I'm going to hold final judgement till I see it in person.
I like odd things so my first judgement is I just think it's going to look cool as hell. Getting off Space Mountain and going right onto Tron is something I'm looking forward to as well and unlike other people, I see that as a reason to be excited and not just complain about how it doesn't fit
EDIT: To make it more clear, what I'm trying to say is for me the fact that I'll be able to get off SM and go onto Tron is great and outweighs the negatives that others bring up that it's dumb to have two indoor coasters next to each other and the architecture differences
