Firstly, let me qualify my opinions henceforth as a person who has yet to neither read the book nor watched the movie.
However, I have no doubt that it is a touching movie that only the love for dogs and bonding with them can provide.
And that, I think should be as far as it goes --- a celebration of bond and love.
Nevertheless, we shall be seeing spikes in purchases of Labrador Retrievers and subsequent abandoning. Misguided couples and over-pampering parents do not understand that whatever on-screen antics by dog actors perceived as naughty and cute translates into very tangible behavioural and social issues in real life for themselves and their children.
I can only hope that aspiring owners take heed of the author's warning before taking the plunge into what should be a long-term commitment of care and attention in return for undying devotion, love and loyalty. (See my other post)
