Slow cinema:
Slow cinema is a genre of art cinema characterised by a style that is minimalist, observational, and with little or no narrative, and which typically emphasizes long takes. It is sometimes called “contemplative cinema”. [Wikipedia]
Noted in “‘The End We Start From’: Slow cinema’s version of the apocalypse,” Michael O’Sullivan, WaPo:
You could also call [The End We Start From] — directed with a slack sense of urgency by Mahalia Belo, making her theatrical feature debut, and written by Alice Birch (“Lady Macbeth”), based on Megan Hunter’s 2017 book — slow cinema’s version of a post-apocalyptic thriller. Paradoxically, not juicing up the stakes with expensive effects and emotional baloney has the effect of making the situation seem at times more, not less, dire. Comer is especially good at conveying a sense of genuine, if weirdly relaxed, panic.
