What the heck was this? A random, inconsequential Episode 3. Quickly starts out like Benidorm meets Aliens then a random bunch of old / new / dressed-up folk end up in tunnels doing nothing in particular because of nothing in particular. Extremely poor concept, characters, script, structure and direction. Looks cheap as heckuva bit less and only Sylvester McCoy and Bonnie Langford would have made it better with some sweets.
