Josh Hutcherson [SEP] 2002–2010: Early roles
The film received mixed reviews, although critics were favorable to Hutcherson. Following the film, Carrie Rickey of "The Philadelphia Inquirer" referred to him as the "Jodie Foster of Generation Y", remarking that with "each successive film Hutcherson dives deeper into his reservoir of shame and hurt and hope, unnerving for one so young, but also unusually urgent for an actor of any age."
