The writer did an amazing job with the pacing and story at first. After I finished episode 4, I had no idea how the story could be stretched into 16 episodes because each episode, each scene, was packed and had a purpose. The characters are very realistic and three-dimensional. The female lead is especially well written. She's a true independent and strong woman rather than just having a snarky attitude and yelling "YAAAA" all the time. Her internal struggle was captured excellently. Overall, the story and writing are consistent throughout. Except, some people (including me) noticed that the vibe was "off" in episodes 12 & 13 (this may be because the first 11 episodes were of such high caliber and episode 11 was a sort-of climax). Episodes 14 & 15 picked up a bit and were good by kdrama standards, but nothing like the first 11 episodes. The ending, episode 16, may be controversial depending on your taste.

**When I first finished episode 16, I thought it was an alright ending, a little disappointing, but light years better than most dramas. Then a week went by and I HATED the ending. Now, I think it's the most perfect ending I've ever seen and rewatching the last two minutes always makes me cry. Even if you don't end up appreciating the ending, it won't ruin the first 15 episodes.**

The cast is PERFECT. The leads are amazing together, they have so much chemistry as a married couple. Lee Joon Gi was phenomenal, and I loved Moon Chae Won. Just the fact that the two are acting together makes Flower of Evil a must-watch. The child actor who plays their kid daughter is so so adorable. The villain gave me the chills. The way he BREATHES makes me shudder. Watch it for the villain.

The OST hits different. The songs really capture the unique relationship that is portrayed in the drama between the leads, which makes them unforgettable. The OSTs are also used appropriately and sparingly for maximum feels. I sometimes wish there were more songs in the soundtrack like a traditional kdrama, but then I realize that Flower of Evil was never meant to be a regular kdrama. It's perfect.

At first, I was let down because Flower of Evil wasn't more of a romance (umm, because LEE JOON GI. He is soooo swoony-worthy), but after watching, it becomes clear that it's much more than that. It's a mature depiction of love between a married couple who have to overcome a multitude of challenges so that they can love each other in peace. Even if they aren't together in every scene, it's because they are fighting to be together, for the life that they have created. It's beautiful. Go watch it.
