Hudgens reprised her role as Gabriella in "High School Musical 2", released on August 17, 2007. The premiere was watched by over 17.2 million viewers in the US, almost 10 million more than its predecessor, making it the most-watched Disney Channel Original Movie of all time. Disney Channel aired a weekly program called "Road to High School Musical 2", beginning on June 8, 2007, and leading up to the premiere of "High School Musical 2" in August. The show offered viewers a behind-the-scenes look into the production of the movie. The world premiere of the opening number "What Time Is It" was on Radio Disney May 25, 2007, and similarly "You Are The Music In Me" premiered on July 13, 2007. The film was generally well received by critics. "USA Today"'s Robert Bianco awarded the film three stars out of four, saying "High School Musical 2" was "sweet, smart, bursting with talent and energy, and awash in innocence". While critics enjoyed the film, they noted that the timing of its premiere seemed odd, premiering just when school was about to start up again, while the plot involved the gang going on summer vacation.
