The film introduces us to Ian, a man so consumed by his career and the "logistics" of life that he forgets to actually participate in his relationship with Samantha. He loves her, but he doesn't know her. He is physically present but emotionally miles away.

It’s a cliché until it isn’t. The film forces us to confront the reality that we don't always get a "Day 2." Conclusion: Love Without Reserves

Samantha just wanted to be heard; Ian only started listening when he knew her voice would soon be gone.
