I watched 500 Days of Summer with the commentary for the first time during this ride. It causes serious reflection and realization even more with the commentary than without. There are very few movies that I feel have taught me something that is really true, but this one does every time.
That's the heart of what this movie's about, the subjectivity. That reality might seem a certain way at a certain time, but you think about it at a different time and the reality might not be as solid as you thought it was.
We live life with a subjective lens, and its tint isn't always rose. I wonder how often we see events for what they actually are, or how possible that actually is. There is always a vantage point, and that changes your view.
