Fuck it, five stars.
Amazing journey you've taken us on here man, I loved it.
Funny, peaceful, somewhat sad. I think it had it all.
Great animation, no doubt, and nice use of little to no dialogue.
Going through the war zone was the best bit for me. I liked how the Soldier commandeered the boat, or perhaps even let the boat take him to where he needed to be. It seemed to give the boat some purpose, or rather, made it appear that the boat runs it's own course, and allows you to interact with it should you wish to. And on it's second visit, I think it earnt respect from both sides. Excellent bit of camaraderie between both sides. Kinda reminded me of WWII, where Allies and Axis played football together on Christmas day, over no-mans-land. Reminds you that there is some good in men, even when we're at our worst.
Shit, get that boat going around our world for real, IT'LL SOLVE ALL PROBLEMS!
