What is the best sequel of all time?

If we're to ponder the question, "What is the best sequel of all time?", we must first acknowledge the subjective nature of such an inquiry. However, let's delve into it with an open mind. A truly exceptional sequel must not only build upon the foundation laid by its predecessor, but also exceed expectations in terms of storytelling, character development, and emotional impact. It should evoke a sense of familiarity while presenting fresh, engaging elements that keep audiences captivated. Now, imagine a sequel that seamlessly integrates into the original narrative, enhancing the world-building and deepening the thematic explorations. The characters, both new and old, feel fully realized and their arcs progress in satisfying ways. The plot is tightly woven, full of surprises, yet coherent and logical. And most importantly, it leaves a lasting impression, staying with you long after the credits roll. So, which sequel, in your opinion, achieves this level of excellence? Is it one that pushes the boundaries of its genre, or one that perfectly encapsulates the essence of its predecessor? The answer, of course, is subjective, but the conversation itself is certainly worth having.
