Well if you get to see the real thing at Animal Kingdom.......
For the little ones, Jungle Cruise is better... as they don't really get that these are not real animals. Yes for us adults it a little boring and corny - not sure how first time visitor view this old ride. But those of us that grew up on it, want to see it stay. Plus a good Skipper and some audience participation can go along way in making it a fun tour of Adventure Land. So an update to fix things that don't/haven't worked, and to make things more life like.... would be a good thing in my view. Especially if the Volcano rumor are true... might also add a new element to the JC.
