So many tenuous and unlikely threads. Boring mystery, leading to boring mystery. Non-sequiturs that you're meant to follow as if this is a serious programme for adults. “I’ve been watching all this time. I know how to keep myself hidden. This is a mystery which spans hundreds of years and every corner of the planet.” It so desperately wants to be epic, complex and impressive. But it's just generic and dull. We’re a long way from Weevils now. The show has lost all of its identity.
