What did I just watch? No, seriously. Can someone tell me?

Rating: 2/10 (6 July 2017)

My "spoilers" aren't actually spoilers. But they may clue you in to scenes in the movie and the overall direction the film takes. That is all.
Now, where shall we begin?
What did I just watch? A horror movie? An action flick? A biopic? An auto-biopic? A documentary? A mockumentary? A Disney nature film from the 1960s? An acid trip? A war movie?
This movie has literally no idea what it wants to be or how to get there. The amount of plot holes and unanswered questions is astounding.
Who was that person? They are gone now and we never learned anything about them. Where did they go? Wait, where did that horse come from? Whoa whoa, we only spent 15 minutes in the jungle and you're telling me that was supposed to be 3 years? How did they survive? Why are they traveling down the river when they are supposed to be going up the river to find the source? Why do all the "Indians" in the film, in remote unexplored areas, speak Spanish? WHAT IS EVEN HAPPENING?
