The first half hour started very cheesy and overly humanizing the dogs however as the plot progressed it got more and more interesting and touching urging you to cry.
Overall it's a good movie and you gotta watch it all the way to the end to get the purpose of it.
The effects were quite impressive, like a very high resolution animation movie however, it still felt artificial in a way whether because the animals were too humanized or just because it is literally artificial
