The six episodes of the first season are complete thriller. If you are a casual watcher and not a critic, you will love the series. Every episode kept me curious about what would happen next. Although there were few loose ends with respect to the facts established.
CONTAINS SPOILERS
1. Every episode had a flash back of characters involved, except the last episode "Terenzio". It would actually help understand the motive of Major Terenzio, which was unclear throughout the series. 2. How did Yakub find Sylvie at her house? It was a detail nobody could've missed.
3. At Brussels for second time, they had half hour before sunrise when they took off. How could they possibly reach Bulgaria (east of Brussels) still in the night? This was one of the loose end of the plot.
4.The amount of story squeezed in the sixth episode could have easily been stretched to seventh or even eighth episode, with more thrill towards the end. 5. When Zara told Ayaz to save her kid as she couldn't make it, I expected her character to die in the end, just to give the story a tragic pause before next season.
