It is a personal thought.
The movie is about dogs. What dogs feels about their surrounding world.
Rebirths of dog shown to describe different aspects of dog thinking. It makes you weep everytime when dog dies.
The plots of movie are poor which unable to make a regular connecton with viewers.
Story is very poor it chould be better.
But some scenes of movie are very touching making worth watching movie.
All other aspects of are nice.
One more thing is to be notice that a rumour of animal harassment is roaming around very fast. If is true then it is very bad.
