subjective i guess. but also subjective in whether certain attractions need a storyline. IMO rides like Space and Thunder dont really need a storyline even though they have a backstory. HM and Pirates do have a storyline (albeit a loose one, though with the timeline of when the Story and Song of the Haunted Mansion was recorded and released prior to the opening of DLs HM, I still hold that that is the official story). The degree to how Dinosaur and Indy are done, I think those rides really do need an active storyline with the speed at which they progress and the way those rides are disigned. With HM and Pirates you have the luxuary of traveling at a leisurely pace in which to take in a whole lot more than you do with Dinosaur and Indy.
Also IMO, while it's nice to see some of the effects from the Indy Trilogy used in the ride as mentioned with the boulder and running through the darts, those are nothing more than just effects, they don't tie together a story. I feel like they simply just put in what everyone thinks when they think of Indy...Boulder, Darts, Snakes, dark forgotteness.
I really think we should just agree to disagree on this one.
