I thought that would be obvious. When United Technologies left TLS an un-sponsored orphan the pavilion degraded quickly. The sea cabs went bye-bye, the activities were out dated and barely functional and guest traffic went in the toilet. Then a great original attraction featuring a certain turtle was put in and life began to creep back into TLS. When this certain turtles clown fish friend showed up TLS almost instantly became one of the more popular places in Epcot. We got the sea cabs back along with a new dark ride, the displays are fun and interactive and the place is always packed. The only thing I regret was the loss of the Hydrolators (which IMHO was one of WDI's best illusions the have ever created) and the film the Deluge. If WDI could somehow fit in a small theater showing Deluge that you enter via a hydrolator The Seas would be just about perfect.
I have no problem with Turtle Talk I think it fits fine, and works well as an accent to TLS like Circle of lif worked well as an accent to The Land. My whole problem is not the fact that they used Nemo, but the fact that they dedicated the whole pavilion to him.
