5 Things That Need To Happen In Kong: Skull Island

Not explaining Skull Island will keep the movie engaging. Part of what makes this location interesting is that it's not part of the world; it's something undiscovered and unique. Any hints to what the island might be should be shown with its design, population, and monsters, not through a character delivering exposition.

When the original King Kong came out, the surface of the world wasn't fully mapped: at that point in history, an undiscovered island was fascinating and mysterious. Although unlikely, something like Skull Island could have existed in 1933, and by the 1970s when Kong: Skull Island is taking place, the fear of an undiscovered island won't be something the filmmakers can rely on.

It would be far more interesting to have Skull Island be something that can't be explained and that some government organization is trying to hide it away from the rest of the unknowing world.

Any explanation would make the island less mysterious and therefore less interesting: questions like why is it there or how the monsters exist should be left up to the viewer. Let Skull Island have some wonderment and make the audience imagine what could be there.
