I am fan of the work of TRON:LEGACY. Daft Punk did the music, which was really done well, great cinematography, and well I love Jeff Bridges. The movie is just visually beautiful to me as well.
The reason I don't think it fits are for the reasons posted within this thread, capacity is poor so it doesn't solve crowd issue for MK, as much as I love this franchise, I can't help but think why they choose this instead of a different IP, heck even some of you just admitted to not knowing there was a 2nd film and truthfully, for that plot of land they really could have done something original with a larger capacity that still fit in with the Tomorrowland Theme. Just my 2 cents but damned I am torn because I love TRON a lot.
