It was entertaining to watch once. I don't know if I could recommend this show to anyone because it's hard to say if everyone would find this show worth their time or not.
The "cool thing" that Elba's character can do is Negotiate. His negotiation tactics weren't even that great when dealing with the hijackers. Most of the time they just told him to STFU.
The show never explained how the one guy was able to get the guns on the plane. If he was able to do it, why couldn't everyone else?
The last couple of episodes shows the motivation behind why the criminal mastermind put this plan together...and man was that underwhelming. How many movies have done the same exact plan? What a letdown.
