You stated that you think "time was an over blown as an issue". My post was in response to that. There was no comparison to the E-tickets and the Avatar boat ride. Not sure where you got that.?. My point was that if these E-tickets were shorter, they would not be E-tickets. Ride time does matter.
Let's look at Pirates. The WDW version of Pirates is the one I grew up with and love, but when I went to DL, it was obvious that the DL version was better and a lot of that is because it is longer and therefore more immersive. I can lose myself in the DL version. A 4-minute version of SSE would not be the same attraction. The same with the other E0tickets I mentions. Length helps the guest be more immersed and helps the Imagineers tell their stories.
Let me ask you this
@GoofGoof... If you were an Imagineer and were trying to make an immersive ride... Would you a want to tell that story in 4 minutes or 8 minutes? Do you think a shorter attraction could immerse the guest better?
