Ah, Signal, how shall I describe thee? This is definitely my favourite Korean drama, though in all fairness, it's not much of a "drama" per se. The first thing I noticed was that the production value was through the roof; most of the episodes feel like watching an hour long movie, somewhat like the early episodes of Sherlock. The plot is very well structured, and the pacing is excellent, with not a dull moment or any overly long arcs in sight.

As far as the main cast is concerned, all the performances are above and beyond the level that one would usually expect from a Korean drama, especially the protagonist and deuteragonist (Lee Je Hoon and Kim Hye Soo). Cho Jin Woong also delivers a strong and memorable performance as old time detective Jae Han (you'll get it when you watch it). Many of songs that make up the OST are haunting and unique, with relatively deep lyrics. Honestly, it may seem like I am just biased at this point, but I am the type of person who reads the summary for most boring K-Drama episodes and fast forwards through them the moment a hint of something typical appears, and I watched, and relished, every moment of Signal.

The ending was somewhat ambiguous, even leaving open the possibility of a sequel, though I doubt any of us are going to be that fortunate in the near future...but here's hoping.
