The Earl of Sodor is returning to Sodor and needs the engines to help him create a big surprise. All the favourites are here plus a few new engine faces and the story is true to the spirit of the original books yet big enough to keep the action going for a proper movie. The format of the TV series is essentially extended into a (short) full length movie with added songs and a clear emphasis on positive values like "working together". For grown-ups there are historic references to Stevenson's Rocket but generally the target audience is preschool Thomas fans who will not be disappointed. My two year old son was impressed and I was easily entertained enough to enjoy our first cinema outing together.
