A feature debut for the director, Mr. Webb, the film is an odd combination of self-referential, in the spirit of its lovers, and insistently referential in its wink-and-nod homages to such classics as “The Graduate” and “The Seventh Seal.”
The script, by Scott Neustadter and Michael H. Weber, references a lot of movies, from "The Seventh Seal" to "The Graduate," but the one it seems to be channeling the most effectively (and most unconsciously) is "Annie Hall."
Zach Braff’s Garden State may be the closest analog—both explicitly reference The Graduate, that touchstone of generational uncertainty—but (500) Days Of Summer is more thoughtful, and thus more maddening in its shortcomings.
The kickoff entry for the Philadelphia Film Festival / Cinefest '09, (500) Days uses that Miller quotation (loosely) and adds a bit more cultural heft to its helium-balloon romance by referencing the French new wave, The Graduate, and art deco architecture.
For a movie about heartfelt connections, its characters have no depth or substance; for one about love, it has no chemistry or spontaneity; the action takes place in Los Angeles, though we see almost none of it; and a reference to “The Graduate” does the film no favors.
Near the end of Tom and Summer's 500 days together, they go to a matinee of The Graduate, and as they watch the final scene (Dustin Hoffman and Katharine Ross in the back of the bus, staring numbly ahead), Summer weeps miserably, while Tom appears transported by the romance of it all.
