The film became Johar's second major blockbuster at the box office and received positive reviews from critics. Critic Taran Adarsh commented that Johar "confirms the fact that he is the brightest in film firmament. The premise [of the film] is simple, but it is the storytelling that deserves the highest marks." Johar's third directorial venture was the ensemble musical romantic drama "Kabhi Alvida Naa Kehna" (2006), which dealt with the controversial subject of marital infidelity against the backdrop of non-resident Indians living in New York City. The film's plot follows a washed-up athlete (Shah Rukh Khan), whose frustration with his wife (Preity Zinta) results in an extramarital affair with a family friend (Rani Mukerji), a schoolteacher who is also unhappy with her marriage to her childhood friend (Abhishek Bachchan). The film was a major success in India and an even larger success overseas. It received highly positive reviews from critics who praised Johar's departure from the directorial style of his first two films. Rajeev Masand wrote, "Few writers have such solid control over their screenplay as Karan Johar does. Few understand the intricacies of narrative as well as he does. Johar goes from highs to lows, from plateaus to peaks with the ease of a pro. He knows exactly how to turn a seemingly ordinary scene into something special with just that one line of dialogue, or that hint of background music." The script of the film which was co-written by Johar received recognition by a number of critics and was invited to be included in the library of the Academy of Motion Picture Arts and Sciences. Johar's fourth directorial venture was the social drama "My Name Is Khan" (2010), his first film not written by him. The plot follows a Muslim man with Asperger's syndrome and his Hindu wife, played by Shah Rukh Khan and Kajol, who live in San Francisco and face racial prejudice after 11 September attacks. The film became a major commercial success, and received rave reviews from critics who praised Johar's unconventional directorial style. Critic Subhash K. Jha wrote that the film "is a flawless work, as perfect in content, tone, and treatment as any film can get." The film won Johar his second Filmfare Award for Best Director. For his next feature film "Student of the Year" (2012), Johar chose not to cast established actors for his lead roles and instead recruited three debutante actors (Sidharth Malhotra, Varun Dhawan, and Alia Bhatt).
