This is another beautiful movie that doesn't have enough reviews, so even a single low one can drop the overall number. For anyone who's ever had a pet, this is a must watch. I don't want to spoil it for those who haven't seen it yet and are encouraged by these reviews, but it's a lot better than another movie I saw about this subject. Really hits home. The story is simple, but effective, and I love the creative use of it's wild animation. I do not understand how more people have no heard of it.
Warning: the very little ones may not like it. It gets a little weird and depressing. Still, if you're an animal lover, find this on whatever streaming channel has it at the time you're reading this and watch it.
