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.
Potential ideas for the feature could include a new antagonist with a personal vendetta, deeper exploration of Tarzan's childhood trauma, and a more nuanced portrayal of the jungle's dangers. The user might also appreciate a darker tone without losing the emotional core. Adding elements like Kala teaching Tarzan the ape ways could be a good angle.
"Between two worlds, he must find his own."
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.
