The first half was generally quite enjoyable, but the pace just dragged to a halt around episode 20 and the story never really recovered. I don't think I've ever seen any drama that abuses flashbacks the way this show does. The amount of filler time is just insane, and it completely kills any momentum. And all of the pacing problems are made worse by the story not being at all creative to begin with, so the margin for error was always low. There were way too many scenes of characters just going around in circles saying the most cliched lines possible.

I generally liked the acting here, and visually it was quite impressive. But the story is just so poorly written, it really lets the actors down.
