Peter Ericson’s review published on Letterboxd :
Watching this fascinating, Oscar-winning documentary about the Woodstock Music and Art Fair, which took place between August 15 and August 18, 1969, is an immersive experience of a rare kind. At 216 minutes, it is the longest film I have seen in a theater thus far (I recently had the opportunity to see it on the big screen at a special screening); however, I was genuinely surprised at how fast the hours went by. Historically and culturally significant, the film strikes a nice balance between stirring musical performances and interesting interviews and behind-the-scenes sequences, successfully capturing and conveying some of the atmosphere of the festival. Directed by Michael Wadleigh; Martin Scorsese and Thelma Schoonmaker served as assistant directors and editors.
