Up until now this series has been suffering from the 'odd-numbered sequel good, even-membered sequel bad' syndrome and so I approached this latest entry with caution. I needn't have worried. This is a well-made, entertaining and memorable film which will appeal to people of all ages. The Lone Dinosaur (based on the Lone Ranger) is a particularly good character and the dream sequences add a surreal edge to the film. A must-see.
