The Lion King is not entirely an original story. It takes inspiration from various sources and incorporates elements from different tales and folklore.
One main theme is the circle of life. It shows how all living things are connected and how life and death are part of a natural cycle. Another theme is leadership, as Simba has to learn to be a good leader for the Pride Lands.
Well, Rafiki is a very memorable character too. He's the wise old mandrill who has a deep connection to the spiritual side of the Pride Lands. He helps Simba find his way, both literally and metaphorically. The lionesses in the Pride Lands are also memorable as a group. They are strong, independent, and play important roles in the functioning of the Pride Lands, whether it's hunting or standing up against Scar's tyranny.
One major difference is the visual description in the 2019 novel. It might offer more detailed descriptions of the Pride Lands, like the unique features of different areas within it. Also, the character development in the novel could be more in - depth. For example, Simba's internal struggle might be explored more thoroughly through the written word compared to the original story which was more shown through animation.
The 2019 version of Lion King has the same story as the classic one. Firstly, it maintains the key events such as Simba's father Mufasa's death which is a very crucial part of the story. Then, Simba's self - discovery during his time away from the Pridelands is also the same. Also, the final showdown between Simba and Scar to take back the throne for the good of the Pridelands and its inhabitants remains unchanged. The movie stays true to the original story's essence.
The new Lion King isn't a carbon copy. It takes the core story and gives it a fresh twist with updated visuals and perhaps a slightly altered narrative approach.
One of the moral lessons in the Lion King original story is about taking responsibility. Simba has to face his past and take on the responsibilities of being king. Another lesson is about the cycle of life and how everything is connected in the ecosystem of the Pride Lands.
