I am moving through shades of a grey rainbow of dull disbelief whilst watching Helix towards a black pit of despair. I liked the first episode and then the second episode, but then? Then something began to slowly disintegrate - logic. No internal logic to the story, no playing against an established logic, no appeal to general logic. The drama in a CDC based drama would, you would think, depend upon having an accurate picture of the CDC; at least something credible. The music choices are often genius - that's a silver lining.
