Am I the only one that genuinely loved Alien Encounter and would think it would be perfect just to bring that back? It was the perfect antidote to the plethora of children-centric rides at MK these days, and helped bring balance to the park. It was cool. And, yes, it warned you that it would be scary and have moments of complete darkness. If people chose not to read the warnings, they did so at their own peril.
By the way, I for one HATE rides like Kali because I hate to get drenched in any park other than a water park. It is an open invitation to chaffing and a miserable latter part of the day, unless you take time to go back to the hotel and change. That, on top of the fact that they have had the same ride at Busch Gardens and Kings Dominion for many years before this one, makes it a none-and-done for me, although I might try the queue since you all like it so much.
