I wish Twister would go, although for the life of me, I can't think of anything decent to replace it with in that small space, other than Sharknado! (Twister AND Jaws combined!)
Kidzone should definitely stay, because there is really nowhere else in the park for the little kids. It's a wonderful area, the ball factory is tons of fun, and it is not very busy. Maybe a new show to replace Barney is in order, but the parks needs something for small children (this, coming from a person who can't stand children).
Fear Factor-yeah, let's bring in a new show.
I love Disaster, and although I am not a fan of Animal Actors, it's nice to have a show like that in the park. Same with Shrek.
