This seems like Turkey's answer to the great German series "Dark". Both involve a confounding circumstance where time is warped and multiple timelines get all mashed together and changed. Whereas "Dark" kept itself in a science fiction mode, "The Gift" utilizes Turkish mysticism as the mechanism for the reality upheavals that occur in the series.
The one thing the creators of "Dark" made sure was that there was some overriding structure to the frequently confusing events in the three seasons. So confusing that the creators have a website so you can try to make sense of what happened. It's a dense read but they did figure it out. Unfortunately I can't say that the creators of "The Gift" made the same effort. What was interesting and compelling for the first two seasons, flounders as soon as the third season gets underway. It's so bad that I came here to get reassured that I should stay with the series but unfortunately it seems my suspicions are accurate and it's time to bail. It's unfortunate as the first season was so promising. This is not the first high concept science fiction program to go awry like this. Maybe next time before putting all this effort into a series, the producers will make sure they've got the story arc right.
