Agree. Too much was happening and I had no clue WHO the movie really was about.

I couldn't possibly disagree more.
White, Exeley and Vincennes are like the corners of a triangle, they are all very different characters with very different motivations, that all experience major character development before this film is over. They are holding the shape of the movie, interacting and balancing each other and the convoluted plot they are uncovering.
This movie is a masterclass in storytelling, and film making. But, I'm biased. This is my favorite movie.

I thought it was very interesting actually. Thanks for reminding me that I should watch it again.

It's on my list of favorite movies and I love the way the primary characters interact. Sorry.
