In season 1: The introduction threw a wild scenario with a big stretch which helped attracting the viewers but the drama didn't return to the main case until the last 1/4. Meanwhile, it added fillers in the middle with okay cases but nothing interesting or outstanding like the initial jolt of rush, however, these middle parts helped connecting the characters together and form their relationships. The male lead character played out well with the setting and Park Shin Yang did a good job with his portrayal. The female lead was the most useless character in the drama. She had no role to play in anything other than being an insignificant side character. The return to the main case was good but unfortunately the drama went a bit soft in the punishment of the culprits. Moving to season 2, I'm sure that season 2 is the worst non-consecutive sequel I've seen in any drama series ever. It's truly impressive how these seasons were in stark contrast to one another. Season 2 had a bad introduction and setup right away. There was a big disconnect between the male lead and his struggles. Which couldn't achieve the same impact as season 1. Everything the drama built, developed and achieved in season 1 was neglected in season 2. All cases were random generated garbage with little to no coherency to its theme, story and character. The male lead character was almost nothing like season 1. They went as far as erasing his past. He became a new character played by the same actor. It's a good example for how a character can change with a different director/writer even when hiring the same actor. Other than the 2 main lead, the drama had a full list of immemorable selection of cast members, completely blending into the background and turning into a white noise mush. Right from the beginning the female lead was the antagonist here but the drama built her story and character in a comical cheesy wronged by society kind of way. Her character had no real weight and ended up falling flat despite being played by a veteran actress Go Hyun Jung. The drama's attempt to make the viewers sympathize with her case and struggles at the end with an emotional climax was unsuccessful. If you really want to watch season 2 then don't watch it immediately after season 1, come back to it a month later because otherwise it will ruin your experience with season 1.
