In fact, establishing a theoretical system is not inherently difficult. The real challenge lies in achieving self-consistency, inter-consistency, and diachronic-consistency in its logical structure. An even greater challenge is applying it to solve real-world problems. The most daunting task, however, is subjecting its validity to large-sample randomized double-blind controlled trials. Of course, the ultimate difficulty lies in integrating its foundational content—along with the ineffable profound emotions associated with it—into a cinematic narrative.
