Sarah Sketcher’s review published on Letterboxd:
Kristen Stewart is spellbinding as a tragically sad Princess Diana on the verge of collapse. Her fantastic performance is complimented by Jonny Greenwood’s intense, manic score.
Slow and meandering at times and heavy handed at others, though I think Spencer is a hauntingly beautiful slice of Diana’s life, I am not sure it fully succeeds in what it sets out to do.
