“My Best Friend” (** out of four) was a treacly children’s family drama about a young girl (Alexis Rosinsky) who moves from the big city to the country where she is a fish-out-of-water but is determined to settle in and assimilate herself with her new surroundings and friends at school. Aww shucks- did I forget to mention that she befriends a talking horse on the farm who gives her sage and guiding advice? Pleasant enough but unexceptional mixture of teenage drama, family comedy, and small-town melodrama. Kids may like it anyway. One-time “Dukes Of Hazzard” siren Catherine Bach plays the young girl’s grandmother who disappears from the story way too soon.
