Freeman Williams’s review published on Letterboxd :
Generally considered to be Chaplin's masterpiece, not least by himself. The Little Tramp finds himself smitten by a beautiful young flower girl, who is blind. She thinks the Tramp is a millionaire, and he sets out to gather enough money for an operation to give her sight.
Chaplin's technique, honed by many years, is perfect. His timing, his presentation. That this silent movie premiered two years after The Jazz Singer and still did well attests to that quality.
I, personally, find it a little too mawkish and sentimental for my taste. Still, I found myself in tears at the end. If you do not, you are a person of stone.
