A married tour guide with a daughter seems an unassuming guy but it turns out he has a particular set of skills honed over a lifetime which make him a nightmare for bad guys, and his friends, too, whom he seems to be trying to get killed. If you don't do what he wants, he will search for you, he will find you, and he will kill you.
A decent show but Segev and many others keep making silly moves. Segev is stupidly confrontational with everyone he meets. We're supposed to excuse this because his wife died. He's very demanding of his friends without offering much to them in return. He also seems to make little effort to hide or conceal himself yet the authorities are mostly unable to find him, or hold him.
The show is filmed mostly in darkness to contribute to the serious tone? The serious tone is supposed to make the audience take everything seriously, but the show could use some comic relief.
