Though not necessarily a go-to experience for me, I quite like what they did with Sub-terra, and I think that attractions like that do have their place in the park for sure. If they were going to do anything to it, I'd maybe want them to bring the story a little more in line with the original Nemesis story (I assume pretty much everyone in this formal has seen the film they made for that in the early nineties), and then have it act as more of a pre-show than a stand-alone attraction. If it becomes a sort of 'extra' to the main ride, then people who experience it for the first time are far less likely to be disappointed with it when it's not what they expected. Because of where it is positioned, i.e. before you enter Forbidden Valley proper, you would go through this part and hear and feel the monster before you see it when you come out and turn the corner, and the sculpture would have much more impact that way (It's a psychological technique used a lot in horror films to tease one sense at a time, with vision last). Would you believe that some people don't even really acknowledge the giant pink thing in the middle, they are just interested in the ride itself, which is a shame. But considering how much they spent on sub-terra (did they all it a 'medium term investment I think?) I think it will be around for a while.
