I wouldn't want an 8 minute Tower either. I was referring to immersion on the ride. ToT is a fully immersive ride despite being shorter and having a thrill component. It's accomplished through a flawless combination of queue, pre-show and ride itself.
Also, you listed a bunch of mega e-ticket rides in SSE, Pirates, HM, Splash and Great Movie Ride. If the boat ride was the e-ticket and headliner for the land I could see comparing it to them, but it's not realistic to expect it to stack up to them.
I think Kali could be a better comparison to this but hopefully a little longer with less abrupt ending.
