It's summer, it's hot, you are on holidays on the beach, you got a cheap book at the kiosk, it's a thriller you sit down and read it. You know it's not high literature, but damn is it a page turner? This is exactly what the Frog was to me.

As a short thriller it works, it very well filmed, the locations are beautiful, it keeps the tension and the acting is excellent.

It has its own flaws and some parts of the plot don't work out well, but in general it's very enjoyable. And since it's so short, it's free of filler content that would have maybe dragged the plot too much.

My favorite story was in fact the 2000s murder case, I feel it was better set, the story was darker, and the delivery of the revenge was better. Episode 6 stands as my favorite episode, it's pure action, like almost a spy movie and the build-up, learning that Giho did see HyangCheol, and pay-out, when he calls himself the ghost and Hyangcheol recognizes him, to that small smile on Giho's lips, it's great. That and the conclusion of Giho crying, finally or somehow free of that burden. I don't know, to me, it worked better than the main storyline.

But the main storyline was also great, specially because of the acting between Go Min Si and Kim Yoon Seok,.
