Yes the movie is complex and I understand the point that some people made where they say that audiences have been fed easy-to-understand movies in the past. But aside from the complexity, the audio of the movie was VERY loud during action scenes
(I wanted to cover my ears in many instances). The dialogue was way to hard to understand and follow. I constantly had to use all of my focus and attention in prder to merely keep up with what was going on. Over all a bad experience for me 6/10.
