If you're looking to make Citizen Kane or North by Northwest, sure.
If you're looking to make multi-billion dollar, multi-decadal loved series like Star Trek, Star Wars, or Avatar, then you bet it just takes stunning special effects. Plots are kept simple or trite, but the effects and cinematography are so stunning that it builds a legion of followers, across generations.
Besides, the plot is basically the same as “Pocahontas”.
I have yet to read what part of the park this will be in. There is a large open area behind India that could be converted, or, it could go behind Dinoland USA (my favorite part of the park).
Will I go there? Certainly to AK, but Avatar? We’ll see what the Annual Pass will let us do.
