To be honest, I was a bit iffy on deciding whether or not I should watch this season since Jang Hyuk wasn't gonna be around. Hyuk's whole "mad dog" personality highlighted the first season for me because it complimented Lee Hana's calm nature and showed a good balance in strengths between their characters, but I didn't want an exact replica of his character in season 2. However, after watching Voice 2, I think Jin Wook's new character brought in a whole new dynamic Jang Hyuk's character didn't have, and it kept me on edge this season. The psychopath is revealed fairly early on compared to last season - which may be a turn off for people, but trust me: although you know who the killer is, you don't know why he's committing crimes and targeting the main leads; and there's twists here and there that will leave you wondering if he's the only psychopath taunting the Golden Time Team. Kwon Yool is amazing at playing his part - so much it freaks me out. I'm left wondering after every episode who's good and who's bad and just what exactly the motives are and it's overall pretty exciting.
