This series is very exciting. To emphasise a point about the bad reviews, a reviewer said the acting was bad. Ruby was given an award for this and her acting as a special needs child is superb. Serena was also very good but Ruby would have been a more difficult role.
All the actors were very good. Their characters were convincing and believable.
It kept me enthralled from beginning to end. Ignore the poor reviews as they are misleading and wrong. The style of acting suited the series as it was a thriller and dangers abounded.
