Having seen the "A-mode" many times in the early days of the attraction, I can only assume that those who claim its too fast and too anticlimactic either never saw it, missed it, of went through the Yeti cavern on those occasional times when the timing of the Yeti's lean and swipe and that of the coaster car were not in sync. When all was working perfectly, as the train careened through the final room, the hulking figure, fully lit and especially ferocious, actually lurched out of its cave, leaned over and swiped at the heads of the riders. It was a SPECTACULAR effect. People ducked, flinched, screamed. The speed of the car and that of the AA led to a reaction of "Did that really just happen!?" It was smartly designed to have maximum impact because of the speed and lack of "face time. " Those of us who bemoan the broken effect are those who were impacted, impressed, and amazed by the sheer audacity and brilliance of Disney at its finest.
