Matt Singer’s review published on Letterboxd:
"Llewyn is the cat."
Even richer on second viewing. I feel you could watch this movie 100 times and not reach bottom. I laughed more, and I was moved more, and one performance choked me up more.
Someone needs to do a video essay putting the opening and closing scenes side by side, comparing and contrasting each shot and line reading, and examining what's changed and what stays the same, and why.
