A dog finds the meaning of his own existence through the lives of the humans he meets.
Fun premise, good actors, bad writing. This film seemed to have potential at the beginning but it quickly devolves into a trite action film. Ultimately it's very boring.
I really wanted to like this movie. I feel terribly cynical trashing it, and that's why I'm giving it a middling 5. Actually, I'm giving it a 5 because there were some superb performances.
One of the most extraordinary films you will see this year. Take that as you want.
