— The Guardian
"One of the finest rock documentaries I’ve ever seen."
— Kyle Smith, National Review
"The film is angular and abrasive, exacting and playful, extremely funny and achingly melancholy."
— The Observer
"Rarely does a music documentary so vividly evoke both the artistic approach and the tricky personality of its subject."
— Wendy Ide, Observer (UK)
"Illuminating. A fascinating look at both a venerable institution, the dynamics of working as a multi-limbed unit that’s ruled by a single iron fist, and what it takes to play this type of music."
— Rolling Stone
"'In the Court of the Crimson King' is really about as good as rock documentaries get, in capturing the essence of a group of musicians and how they relate to each other, the world and a muse whose demands result in literal and figurative calluses."
— Chris Willman, Variety
