Sean Gilman’s review published on Letterboxd :
Sylvia Chang makes a movie about Sylvia Chang writing a movie about a failed romance that Sylvia Chang or "Sylvia Chang" may have had with someone who isn't quite Takeshi Kaneshiro. A span-the-decades romance along the lines of Comrades, Almost a Love Story, with the two lovers occasionally resurfacing in each others' lives some years down the line. 20, 30 40 pulls kind of the same trick, except it's about three different women (or at least three different actresses) at three different stages of their life (20s, 30s and 40s, of course). Sylvia Chang has a temporally expansive view of love.
