It has its faults, but quite enjoyable, The basic plot appeared rather silly and there were weak story lines, ie train staff are sent to search the entire train for a lost boy, but nobody suggests that telling the driver that there is more significant problem would be a good idea, especially when he still had control of the train. But this is the first of six episode, and there was a clear attempt to build up suspension which certainly got me wondering who was involved in the hijack and what twists might come. Well worth watching the next episode... I hope
