'Younger Brother') is a 2024 American coming-of-age comedy drama film, written, directed, and produced by Sean Wang in his directorial debut.

Chris regularly uses social media to escape from his underwhelming childhood and overburdened mother (Chen), but the Internet also accentuates his preexisting feelings of internalized racism and personal inadequacy.

[4] In the summer of 2008, 14-year-old Chris Wang (often called Dì Di) lives in a middle-class neighborhood of Fremont, California, with his Taiwanese immigrant mother Chungsing, her demanding mother-in-law Nǎi Nai,[a] and his older sister Vivian.

Chris rarely sees his father, who has moved back to Taiwan for work and supports the family in America with remittances.

He makes silly YouTube videos with best friends Fahad and Soup, which incorporate a great deal of juvenile humor.

At the mother's suggestion, Chungsing sends Chris to a cram school, where Max's friend Josh ruthlessly bullies him.

In addition, although Nǎi Nai is warm and grandmotherly to Chris, she harshly criticizes Chungsing's parenting and negatively compares her to her absent son.

Chris sees an opportunity to become cool when a trio of older skateboarders recruit him to film highlight reels for them.

[11] Nagata received permission from Future Islands to use one of their albums, but Wang vetoed it as its inclusion would have been anachronistic with the film's mid-2008 setting.

[11] Motion City Soundtrack wrote "Stop Talking", their first new song in over a decade, for the film's closing credits; they got in touch after Wang's Instagram story about their performance at the When We Were Young festival.

The website's consensus reads: "A semi-autobiographical love letter to teenage angst that's also slyly self-critical, Dìdi is a deeply moving personal statement by writer-director Sean Wang.

"[26] Metacritic, which uses a weighted average, assigned the film a score of 78 out of 100, based on 37 critics, indicating "generally favorable" reviews.

[27] In her review for The Guardian, Adrian Horton described Dìdi as "easily one of the best, most seamless films [she's] seen on the experience of growing up online" and declared that it has a "clear antecedent" in Eighth Grade (2018).

[28] Bob Mondello of NPR wrote that the film "has plenty to say about social media changes and cultural identity, and ends up feeling a lot like its pintsized hero – cute, charming, exasperating, promising.
