This show is unique, it sort of crosses the line between variety and drama so basically you get the best of both worlds! It has the tension of a mystery plot where you are constantly panicked your favorite character might fail the challenge and end up losing the culprit and the guilty pleasure feel of a variety show where you laugh your ass off at their dorkiness. By the end, naturally it's not possible to not have a favorite (surprise surprise it was Sehun for me) and no spoilers but I loved that he started getting shady toward the end lol it was so hilarious to watch. Another thing I loved was they don't always necessarily catch the culprit so it was always an intriguing plot not knowing what way a story was going to go. My favorite characters were Sehun (DUH), Sejung, Ahn Jae Wook, Jong Min and I totally warmed up to Park Minyong after a few episodes. Especially how most of the time she was so badass lol and did what none of the guys could do even and add to that her intelligent deductions. Most of the time she was extremely perceptive. I feel like Kwang Soo as usual was more comic relief but seriously their banter made the show so can't complain. That one little tiff between the two groups though when the other run ahead of Jae Wook, Kwangsoo, and Sehun, what Kwangsoo said was I get that he must have felt that way. But when Sehun said it too, seriously I wanted to cry. That was so intense! But that's what I mean in a simple fun manner they give a lot of insight into people's feelings and that as they all continued to go through the challenges. I liked Kim Jongmins role because first off comic relief lol and second um comic relief! Ahn Jae Wook I just thought he was a real sport and had talent as well as body strength and wasn't afraid of going in. I liked that despite being less intelligent than some other characters, he never gave up. Well Sehun also never gave up but pretty sure that was out of sheer competitiveness lol I know everyone was constantly commenting on it lol but God did that make for a hilarious watch. As for Sejung she was absolutely a delight to watch! She was so energetic and full of life and just so sweet. Ok not going to lie I ship SeSe or whatever lol there I said it. Totally wished she called him oppa at least once lol but hey there is always next season. Just going to say that despite the fact that I knew it was a variety show, everyone was laughing but seriously some of the stories were so damn realistic! Especially the vampire one. It totally got to me! I was laughing and crying at the same time lol My favorite cameos were Park Hae Jin and Yoo Yeon Sook. Yoo Yeon Sook was perfect because when you needed him to be serious he delivers and when you need hilarity just put Sehun in charge of him and put him in a bus lol I love that even he couldn't stop laughing at times! seriously I need season 2 LAST CENTURY. But the good news is it being filmed already and Netflix picked it up for a second season, I'm going to try and wait patiently ^_^ seriously just go watch!
