Stephen King's Cujo appeared on screen in 1983 to a shrug from audiences, but it’s held up remarkably well and now stands as one of the stronger films inspired by Jaws’ success with rabid animals. The story centers around a large, friendly St. Bernard who is bitten by a bat, develops Hydrophobia, and then begins frightening everyone nearby. This creates trouble for Donna Trenton (Dee Wallace) and her young son Tad (Danny Pintauro), who find themselves stranded in an old car that has broken down within the dog’s hunting grounds. Lewis Teague directs with considerable ability, creating a lot of suspense and delivering genuinely scary moments as mother and son struggle to survive. Some believe the movie's initial section could be shorter, since it establishes the Trenton family dynamic. Donna is having an affair, and her husband Vic (Daniel Hugh-Kelly) has discovered this, so we spend forty minutes getting to know the characters and their relationships. This works well because once Cujo starts attacking Donna and Tad, it highlights emotional connections not just between the people involved, but also with the dog himself. Wallace and Pintauro are both very good, giving the film its emotional core as they portray a convincing mother-son relationship. Teague also shows some creativity with his camera work, always serving the feeling of being trapped in a terrifying situation. Certain details from the book were omitted, and the conclusion—in my view—was altered, but overall this is a well-crafted horror film deserving another look considering today’s landscape of sequels and reboots. It would have been nice to see more of those bats, though; they're fantastic! 7/10
