Nope, nothing to miss here. Sure, 35 years ago, the dinosaurs represented one of the most accurate portrayals ever seen of what they looked like. Now such displays are very common, just go down the road to Tampa Lowry Park Zoo and they have a walk through dinosaur attraction with much more realistic looking creatures that don't need dim lighting to disguise the work.
The information in the ride is so dated as to be ridiculous. 50 years of fossil fuels and natural gas left as of the mid 90s is laughable. That would mean we have about 25 years left now, and that certainly is not the case. But let's not turn this into a debate about energy usage, I'm just saying the information in the ride is inaccurate.
My biggest nit-pick though is that final jeopardy answer. Dumb Judy actually has the correct response. No form of energy is ever-lasting, entropy ensures that. Brain Power certainly will come to an end when mankind is extinct, which the universe will ensure happens at some point, hopefully some way off point, in the future. Mankind, nor any life form, is not eternal. For a science themed attraction, to get something like that so wrong, I wonder why Bill Nye even allowed himself to be a part of it.
Won't miss it.
