So now I have watched all four series and fairly enjoyed them all. I didn't review the second and third series because my reviews would've sounded the same because each premise was the same.

Even though I watched all four within a two week span, I for some odd reason can't remember who the main male lead was in the second series. I didn't care for the main male lead in the third and I'm trying to figure out if I liked the main male lead in this one. I know I liked him in the Player and I dropped Black...that's probably why I feel the way I do about him in this series. I also didn't know why the creator had the same premise for some of the characters in all of these series meaning: main male lead was angry and didn't want to be apart of the Golden Time Team but ended up realizing it wasn't bad. Each character didn't believe the hearing ability of the female lead but began relying on her ability in the end. The computer geek who was able to find any everything when it was time and somebody within the police force was crooked. They might as well kept everybody the same in each series because they were the same.

This along with the third installment barely dealt with side cases. It just dealt with them trying to catch the main villain which I didn't mind but I was so use to seeing different scenarios throughout the series and when that didn't happen, it made the series drag a little bit.

My favorite character throughout the series was Kim Joong Ki even though I felt the writer did him a disservice by making him look like a lazy detective turned captain. He did nothing but shout into his ear piece and tell people where to go throughout the whole series. The other characters outshined him but he was still my favorite.

Again this series had some take aways like the last three. The main female lead is suppose to have superb hearing but at times she couldn't differentiate the sounds she was hearing like a click of a lighter....If you're not vision impaired then you would know what a flicking lighter sound like without having to see it.

The last episode wrapped up into what may look like a soon to be Voice 5. This is the first Korean drama that I've watched that actually had more than one series and it makes me happy. I am however, not going to be happy because I don't know if this cliff hanger will actually turn into another series in the near future.
