Series 6 is my favourite for a number of reasons. Firstly, atmosphere. The music in the causeway scenes, the dreadnought and the different outdoor scenes are very engaging.
Gameplay. It is now easy to see what a team is meant to be looking for on each level and adds to the tension if they have to bargain with a character for a particular object.
Last, the teams of this series were, in my humble opinion, quite memorable, especially Sophia's team who were very unlucky to fail at the final obstacle.
