I'm not a fan of TLM (the ride at MK) It's OK and maybe a step up from Nemo but I wouldn't wait more than 5min for it. For as excited as I was about NFL, this ride was a big factor in leaving me with a "meh" attitude after.
There is one thing to consider: It's all taking place in the water. No other ride has to fake animation under the water. You could say, "But what about 20,000 Leagues???" It was actually under the water. The natural flow of hair and other bits look normal in that situation. For TLM, they had to fake it and, all other things considered, I could see how they went with the plasticy-stylized versions of the characters because of it. When you consider the whole "under the water" bit and still making it look right, it's hard to imagine a different way of doing it.
