Big Thunder is a perfect example of how WDI can use theming and set elements to enhance an attraction. By any standad, Big Thunder is a slow, tame, and lame rollercoaster, but because the track is always at "ground" level and is constantly passing by and through huge rock formations, it gives the impression of moving much faster than it actually does. Instead of moving at high speeds through the air on the elevated track of a traditional rollercoaster Big Thunder more closely approximates what people used to driving in cars think of as a high speed, high risk situation. That's why the ride is so exciting. Besides, it's hard to find a cooler sight than Big Thunder at night when the steam rises up from the sulfur pool and wafts over the Tyrannosaur skeleton while the whole scene is lit with otherworldly blue and green light.
