Not a credible 'spy' and too many scenes that add nothing to the story and just pad a sloppy I-don't-know-where-I'm- going-with-this production. Lots of hype because the series is non-western and therefore has somehow a special edge over the Israeli-Iranian issues - does not matter where it comes from if the story is bland and characters are not credible

Good, well acted and great cinematography. A fantastic story that struggles with how to credibly 'explain' the existence of parallel worlds. So, you reach the last chapters and the ending is rushed, not quite tying up all lose ends. Reminded me of Lost - great story that unfolds into the absurd
