I appear to be in the minority here, but I've always liked Indy. True it doesn't really live up to the potential of the franchise, but it offers some nice thrills and is greatly themed. And I love that you can see the temple's upper ruins rise above the jungle vegetation somewhere in the distance from several places in Adventureland. Great cinematic build up.
To improve it though, how about pulling a "crush's coaster"? Like in adding a dark ride section right after the boarding station, and making the actual coaster part the finale? There is room for a show building between the ride and the Explorer's Club, leaving the space on the other side, earmarked for the EMV ride, available.
I agree. I've always thought of Indiana Jones at Disneyland Paris and Raging Spirits as a minor E-ticket attraction due to their great theming (Raging Spirits more so), both in the queue and in the ride itself.
I would go nuts for the Jungle Cruise EMV ride, complete with the rainstorm sequence. More so than for an Indiana Jones Adventure. I'll probably change my mind after i've ridden the latter though (I hope soon!) ....
