Unlike a wordy drama, Apocalypto is a visual hunt. You can understand 90% of the plot through the characters' eyes and actions alone. How to Get the Best Viewing Experience
Until an official anniversary "Director’s Cut" with a dubbed track is announced—which is unlikely—the best way to experience the chase is exactly how it was intended. Grab the high-definition Blu-ray, turn the lights down, and let the Yucatec Maya wash over you. The subtitles disappear into the background once the adrenaline of the jungle hunt takes over.
The specific term "Apocalypto English audio exclusive" might refer to a unique release or feature related to the film's audio for English-speaking audiences. Without more context, it's challenging to provide a detailed explanation. However, the film itself is a significant work in Mel Gibson's career and in the genre of historical action-adventure films.
