Visuals are important. The film's CGI and action scenes might not be as impactful as they could be. Enhancing the jungle settings with better visuals could improve the experience. Also, the user might want a more cohesive antagonist, since the villain in LK21 was criticized. Maybe adding backstory or making the threats more personal to Tarzan.
Themes could be another angle. The original Tarzan stories have themes of identity and survival. Expanding on these with moral dilemmas or the character's growth in the jungle versus civilization would add depth. Including the ape community's dynamics, like Kala's role, could also be a point for the feature to highlight.
I should also consider audience reactions to LK21. If the box office or critical reception was negative, the feature should address the common criticisms. Maybe the user wants the remake to be more in line with traditional Tarzan lore while incorporating modern storytelling elements.
