I loved this movie because to me it's a beautiful metaphorical tale of what it's like to be in love.
It can start off with a simple, kind gesture-and before you know it, you're spiraling into a world of mystery. Love is something we grow up hearing about, but nothing can prepare you for its arrival. It's like a beautiful sunrise, starting off with blushing reds and warmth, slowly enveloping you until you're helplessly soaked in sunlight.
When you're in love, you find a new sun to revolve around, and as much as you can, you want to bask in its light. As you unravel as much as you can about each others' pasts, futures, and destinies, all of the unknowable and unexplained can be daunting. But along the way, you learn that you don't need the answers to everything, the present and your feelings can be enough.
The world around you seems to change and it's not something that's easy to explain. Like trying to convince someone that she's the reason the sun shines, words don't seem vibrant or intimate enough to describe the experience itself.
With time, your relationship evolves to a point where many other relationships have ended. You're asked to commit and to sacrifice. To leap into the unknown. To give up what you have for an unsure future. Logic only points away, but the heart pushes on. You offer up your fears and doubts because you trust that person to be your sunshine, even if it rains for the rest of your life. Even though they have the power to break your heart, you fearlessly leave it in their hands. You defy destiny and deny countless futures for one together. It's scary and worldchanging, but it's beautiful and it's worth it all.
When the world floods and the rains keep pouring, you know that all will be well, because she'll be there, weathering all of it with you.
