Acting skills level high. Other than that: Soundtrack overbearing. First hour its just mumbled talking punctuated by some head ache causing loud metal creeking stuff. Without back story or reading the book you have no idea what they are talking about. I wanted to leave the cinema after first 15 min, never happened to me before.
Cinematography - from a visual perspective its great if you like super dark, as in you cant tell whats happening. So much fighting/explosions/drilling. Just overly focused on mechanical part of the movie. Walked out before the end. I wanted a refund.
