I agree with everyone, I love this ride the way it is. I remember the Pre-Ellen & Bill days and it was soooooooo boring. I fell asleep. I think it's education in a fun way, the jokes hold up even though I've seen it a dozen times. The only thing is... Bill Nye isn't as reconizable as he used to be, I don't believe his show is even on the air anymore. BUT his name is Bill Nye THE SCIENCE GUY, so I think everyone can figure out what he's all about even if they don't connect him with the TV show. Jamie Lee will always be popular, and even Jeopardy has renewed it's fame ever since they changed the rules and what's-his-name won all that money.
If I had to change something, maybe update the animatronics or add some new dinosaurs?
