I watched this movie because I love animals and wanted a break from the violence and gore of most recent releases. It is an oasis of good, clean family entertainment in a market where such products are increasingly rare.
The movie revolves around a border collie puppy born on a spectacularly beautiful sheep ranch near the ocean in the British Isles. As the puppy grows up, there is a question as to whether she can prove herself to be a talented sheep-herder and earn the right to stay with her family. An unusual, and rather old-fashioned, feature of this movie is that while the animal "stars" speak to each other in unique voices, there is no computer-assisted mouth movement or other modern CGI features generally associated with movies such as this. The actions (and accents) of the dogs, sheep, and ducks all fit who they are and what they are doing and saying, and the individual personalities of each animal become well developed. Kids will love this. Parents will too.
The plot contains some suspense, danger, humor, and (warning) the inevitable tear-jerking moment when one of the dogs dies of old age (very nicely handled). The scenery is magnificent, as is the photography, and the script, while a wee bit juvenile, is still better than scripts found in many "adult" movies.
If you have young children and want to do them (and yourself) a big favor, rent or buy this DVD. It is not as glossy as a Disney feature, but has an old-style beauty that simply glows. You will come to love Mist.
