I am very interested to see the changes to this attraction. Although technically this ride appeared to continually improve, it always managed to leave you with the feeling that you missed something. It screamed for attention from it's creators in many areas including the highly important "Keeper" character. This one character had to carry the entire show. Too much emphasis on a redundant human performance in a theme park world, is like placing all of your hopes-for-ride-success eggs in one basket. Why do you think Walt Disney(et al) invented animatronics? There was too much risk that a "bad day" or even a "sick day" would cripple the attractions appeal/success. I can believe that this is one reason for the change of characters, "Keeper" to archelogical dig "worker". By doing this they are also not limited by the gender of the actor/actress that portrays that character.
I do not officially know how many actors actually played the keeper, but it had to be only a handful. With multiple shows, I would only speculate that the daily grind took it's toll on the very few "Keeper" actors.
Look over at "T-2,3-D" and you can tell that there are more than just a handful of actors that can play each of the parts. The lighting and proximity is such that just about any actor can be plugged in to any of the roles.
"Keeper" was a much more dramatically demanding role. He was right next to you. So close in fact that you could even see how bad his wig and beard were. He had to be good every time to make the story believable. Other actors, like in "T2,3-D" are essentially "human animatronics" and can just walk through their performance.
Now with the new "Archelogist" character, they are creating more of a tour guide type character(like the Jaws Boat Captains) that can be played by any person of any gender.
As far as effect improvements, I am interested to see how much better they will get. Upon first viewing(when it first opened) I knew that they had work to do, and they did. It has improved to be a very good effects driven show. I especially liked the vortex, water screen projections, the 3-d laser water screen projections, the explosive way they mixed water cannons/blasts and fire balls, and of course the mysterious finale.
However, the elements I did not like included most importantly the storyline. What a stretch. Like an idea that sounded good idea on paper but just could not be realized by it's screenwriter,director or show producer. I remember hearing RUMORS that prior to IOA's opening, this show went through a dress rehearsal for all of the park bigwigs and they were very unimpressed. And that's a BIG understatement. They delayed the opening and tried to re-work it but it seemed(again from an outside theme park fan, not a insider) like patch work and knowing this you felt like after viewing the attraction it was a "Lite" version of what it was supposed to be or maybe could have/should have been.
The show's whole set up was far fetched and too loosely based in legend/history to make such a giant leap from start to ending. And where the heck did the "Oracle" come from and why was it part of the show? The effect was even of lower quality than you can find in one of the travelling carnival laser shows. It just never created enough anticipation to lead to the incredible vortex effect. Then in the finale room(s?), the story fell short because there was just not appropriate set up. It was almost like each room was part of a separate attraction with it's only link being that they were under the same roof.
Maybe all of this is a little too much to expect of a marquee attraction that is the cornerstone of a heavily themed island in the best theme park in the world, but "They" are the one's that set our hopes so high to begin with.
Or maybe it just might be too much fan speculation mixed in with 20/20 hind sight, but news of this rehab/replacement is interesting to say the least.
Maybe next they will do the same(Rehab/Replace) to the Jurrasic Park River Adventure,
but that's another rant.
HAVE FUN
