Well it started not too bad but slowly and surely lost its mojo by wanting to keep suspense episode after episode it becomes less and less plausible and it's ashame because it's very well filmed. Other plane characters are fine , yet the high jackers are really not very credible and seem amateurish , also Elba loses it from time to time and becomes quite annoying even ..so basically uneven , it seems that his character talks too much ..a lack of pace , a lack of credibility and some very far fetched twists make the whole series berry uneven , so basically very average and disappointing but if you've got nothing else to do , watchable.
