German series don't usually grab many headlines, with stodgy plots and dead-serious characters, but this is somewhat better: decent plot, well-acted and, once you get past the sci-fi hokum, pretty engaging.
Film editing is sharp and glossy, with high production values and some good use of flash- backs. It touches on some vitally-important issues in bio-ethics, but it's not going to win prizes for insight and originality.
Worth a watch.
