The Internship is set largely in the world of Google. That setting provides the background for a story mainly concerned with success and with the effort people make in order to achieve it.
The film also embraces a fairly traditional moral structure. It draws a clear line between good and bad and follows the familiar idea that good actions are rewarded while wrongdoing eventually brings consequences. This gives the story a straightforward and recognizable sense of justice.
At the same time, the movie presents a strongly optimistic view of effort. Its message is simple: people should keep trying instead of giving up. The film encourages the belief that continued effort can make success possible.
Overall, The Internship is a hopeful movie about success, effort, and the idea that people may be able to move forward when they continue to try.
