Glad that someone finally spotted the Friedrich-ish flavour of the shore scene design in MotOE.
The painting conveys a message of Kantian self-reflection, expressed through the wanderer’s gazings into the murkiness of the sea of fog; likewise the Doctor’s dour consciousness of the burden he shoulders in his entire life makes the grandness of his two-thousand-year-old-time-lord soul shine as ever before.
It’s enormously effective because of Capaldi full owning his character in flesh and bones, and also because of the majestic use of camera movements, which make the Time Lord silhouette stand out gigantically beside the tiny, crouched Clara, framed by an infinite, cloudy backdrop.
