Well. having read previous reviews and had watched 3 episodes, I really had the dilemma whether I should continue watching Grid or not. Thank goodness I did! The storyline was very clear from the beginning and you could easily connect all the dots given by the writer, when the appropriate time came to it. Suspensful, full story, no holes in it at all. It kept my mind alert all the time and I had no difficulty whatsoever in following the story. I really do not understand why other viewers found it so difficult and non coherant. The idea of grid was all over the place, it did not fail the story not even once. Another thing that was interesting about it, is how the writer exploited the theory of probabilities and the philosophical question of what time is. She wisely kept a low tone tossing the question to the viewers for the time being. Excellent job, mrs. jakkanim!
I trully believe that it was one of the best Kdramas I've seen so far, and I 'm anticipating season 2. All the hints for season 2 were given from episode 7 and on.
Worth watching it? A profound Yes.
Acting was very good from all actors, many kudos to all of them.
Directing was also fantastic throughout all episodes, especially the two last ones. It was giving the hints of season 2 in a very laconic manner which I loved. Congrats to the director for that and also the writer who had the bouldness to keep it that way.
Finally, the music was auxiliar to the story and not over the top, but I'd rather like one more score than the one and only, just for variety.
Rewatch value, now. Yes, I'd watch it again.
I hope this review would attract more viewers, thank you for reading this.
