The art direction/cinematography/score are all top notch. It's honestly worth seeing for those aspects alone. Many scenes/images that will stick in your head for awhile.
I totally disagree with some of the reviews saying this film is a punishing/boring viewing experience. I was interested and entertained throughout all 2 1/2 hours.
The only reason I didn't love the film is I just felt disconnected emotionally, especially with the ending. Did not resonate. I also have gripes with Tilda playing the old doctor...so fucking distracting and hard to understand.
