Here is a short version of the plot. Percy feels rather depressed because he thinks that Thomas doesn't have time for him anymore. But Diesel, Den, Dart, Norman, Paxton, Sidney and Diesel 10 all persuade Percy to be their friend. But Percy doesn't know that they are just plotting to take over the Steamworks!!!!
This is a really exciting film. True, I think Misty Island Rescue is better, but there are rather dark scenes (dark for a HIT Entertainment at least). It includes laughs, evil, and even some mild horror (for three-year-olds).
If only I could watch this in 3D, or even 4D - that would probably make it even better than Misty Island Rescue.
Most things in it are really excellent. Although this is a five-star review, I was disappointed that Flynn didn't run on roads.
I liked Belle and the CGI animation - I think it looks better than that in Misty Island Rescue, and that was better than Hero of the Rails.
I give thumbs up to this.
