TDLR: Insomnia was a breath of fresh air, consistent with its storyline and gripping for all 13 eps. I can't exactly put into words how absorbed I was into the story.

❛ Story ❜
I love plot above all and the plot of this drama is indeed quite amazing, everything is foreshadowed well and it stays interesting till the very end. When I started it, I wasn't expecting it to be THAT good and even managing to grab my attention with just the first episode.

It's really not what it may seem at first; what appears to be somewhat typical mystery drama about a mundane island in the beginning changes into something unexpected and dark. This is the first drama in which I couldn’t afford to fast forward any scenes because each episode of it kept me on edge of my seat and I loved every second of it.

To some, maybe the plot might be a bit predictable, but it doesn't lowers the enjoyment, it only proves that the plot-twists were believable enough for the viewers to catch and not get confused. Because plot-twists aren't supposed to be confusing, they're supposed to either caught you off-guard or make the story more interesting and complicated as new developments take place (at least that's what I believe, since I've watched my fair share of 'mystery' dramas that are a complete mystery for me to understand...)

❛ Characters ❜
The MC is the best thing about this drama. She's smart, strong, and capable without being unrealistically 'superior' (as in intelligence or other aspects) to other characters. She's exactly what we mean when we ask for a 'strong female lead' - someone who's not necessarily fearless or reckless, but brave enough to face her own fears and do the right thing.

As for others, they were great too! The side characters, whether they're likable or despicable, are really well-written and I love how they're written like actual characters rather than just some stepping stones for the MC. The whole cast also did a great job with their performances.

All in all, I'd really recommend everyone to give it a try! don't let the few amount of recognition it got discourage you because as I said before, it's a lot better than it might seem at a first glance.
