Every week this show gets worse.
An ancient tablet is discovered when a photo-journalist falls down a hole that nobody has found before now. It all ties into Tiamat, Dolly trying (and failing) to be Gene Hunt, a crap CGI snake, hints that there is something up with Vivienne and a cute kid who can save the universe. Also the sub-plot of Excalibur (still they won't say the name) drags on as it is said that the sword was carved from a meteorite. Wasn't the legendary sword carved from meteorite trope already done in the novel 'Riptide'? This was deathly dull awfulness.
