It can be pretty hit or miss when it comes to a Netflix original series, but I loved this one too. It tells a fantastic story, the characters are believable and engaging, and the show is surprisingly funny. I particularly loved Kim Seon-ho. My only complaint is that the ending was predictable. I wish they'd do a second season.
I dont like it when a show only does one season. It's so anticlimactic. If it doesn't have at least 7 seasons, it shouldn't be on.
I'm the opposite. I haven't watched that series because I feel lazy needing to watch a lot of episodes. I'd rather watch movies because the storyline is concise and only requires little time. I'd only watch a series when the plot is very intriguing.
