I don't know about cool. But the movie demonstrated how science, and even individual scientists, can have enormous practical impact, shed light on reality, and raise moral questions of the highest order. That level of impact inspired me to aim at a science career when I was a student, before I found other pursuits more inspiring to me personally.
