Korean Drama " Grid " had a nice, atmospheric start, with a moody story, a mysterious ghost woman, and an even more secretive company that kept the grid (?) under control.

And even though there was potential for this drama, with smooth and excellent performances by the main leads, but also by the supporting cast, and the sci-fi CGI were all well handled, the story was too much for nothing. The main plot didn't make any sense in the end, with all the time-traveling, the grid technology, and the generations' medley. It somehow felt less, compared to what the drama seemed to build up to.

So, overall, 4 out of 10.
