Comment by Magic Marmalade:
MGM tries to do Disney, and misses the mark, somewhat.
Fans of James Herbert's novels will acknowledge this, while not being his greatest novel, does hold a place of deep affection in their hearts... as it is, not his usual horror fare, but more of a poetically tragic tale of a man who, once he dies after a tragic car accident, is resurrected as a puppy, born to a stray, and form there, haunted by memories of his former life as a man, tries to find his way back to his human family.
Already you can see this is a little too heavy for what the DVD cover here suggests.
That seems to present the idea of a more: "Turner and Hooch", or "Beethoven" style "Awww!"-fest. And I think that was what MGM was aiming for: That those kinds of movies were killing it at the box office at the time, tuned in superficially to this novel, as "being in the ballpark" of that kind of story, and so went with it. But while it may be among the more earnest, even tragically sentimental of Herbert's work, it really isn't Disney material, and a little strong and odd for kids.
I made the mistake of watching with headphones on, so all I could see in my head while the voice overs for the real dog's thought dialogue was the image of Samuel L. Jackson in a booth, with fag on the go and a glass of whiskey while he phoned in this afternoon's work for a fat paycheck / paycheque (as you will)... That really breaks the illusion.
(Still better than a modern CGI talking dog effect though... at least it's honest!)
It does engage you more in the last twenty minutes or so though, and is, on occasion there, touching... but that's due to James Herbert's story, rather than the mis-matched Disney style movie presentation, which even that, could not entirely dispel.
I would therefore encourage people to give the movie a miss perhaps - or go into it with no expectations at least - and instead, read the book... It's pretty lo-key great.
