And then the credits roll. Hopefully, these people walk away from the experience with a greater appreciation for their friends and family.

That's powerful. Mark's disappearance actually created a community, bringing together disparate people from disparate backgrounds for one goal—to bring one dorky botanist back home. Most of these people didn't even know him; they probably hadn't even heard his name before. We're getting choked up just thinking about it.
