Story - 10
I liked the plot, it's not something new, but I was very enthusiastic about the idea of Sand Box and the philosophy on which it was based. So for the concept of Sand Box alone I give them a full score. The pace is good (fast enough to not get me bored) and constant. (Actually the main reason I chose this series was because it has only 16 episodes. I don't like those dragging dramas demonstrating to us, again and again, some aspects. I mean how many episodes, dialogues and monologues does someone need to understand a character's depth and complexity? If the script is good and the actors are too, a scene or two are just enough. But if they are not so good, then, irrespective of the amount of time given on screen, they will not manage to convey the message meant to be conveyed. ) I also liked the fact that the love story and the business story were approximatively equally present and they were mixed together beautifully. I laughed, I cried, I had intense moments and relaxed moments; this series has them all and serves them appropriately in terms of time, quantity, quality and logic. I've read some harsh critics regarding the narrative of the plot (actually quite many), but I find them not very befitting. Probably their authors are not very observant of life or maybe they simply lack experience. During my life so far I have encountered every single aspect, situation, action and reaction presented in this series. Yes, they are real and they do occur in life. Just because I wouldn't necessarily act the same way as these characters here, it doesn't invalidate them. I would suggest: be open-minded. If I were to talk about an aspect with which I disagree, that would be someone denying their own feelings. For me it's just so hurtful and unjust. And illogic. But than again, I also saw this happen in my life so... yes, it's real. I myself have done it. I'm not proud, but I also don't regret it (not very much, just a little) because I like to think that I've learned from my mistakes. So whenever I see this cliche in Asian films my heart tightens because I've been there and I empathize quite strongly.
Acting/Cast - 10
Although I'm not a fan of any of them, I must say that the actors are good. They managed to express all sorts of feelings beautifully, especially the inner struggles related to young and inexperienced people trying to start their own business and prove themselves. The 3 boys from Sam San Tech were absolutely adorable. They made me laugh so hard that I woke up my neighbors in the middle of the night. I also liked their emotional side because it's only natural to cry when you feel defeated. I like super strong characters, but I also like those who are nearer to the average human behaviors. Yes, some people are stronger, but some are more sensitive. This doesn't make them less valuable. Of course, Kim Seon Ho outshines them all and he was the only cause of my suffering throughout the entire series. Nam Joo Hyuk/ Nam Do San is adorable but still I was thorn because I would have liked Kim Seon Ho/ Han Ji Pyung to end up happy. And that's only because his acting is so good that it made my heart ache for him so hard. And since I am of a certain age, :) my favorite character in this series was grandma Choi Won Deok/ Kim Hae Sook because she impersonates that ideal of goodness and selflessness which I'm striving to achieve in this life. :) (That was an unnecessary detail, sorry).
Music - 9
To my shame I must admit I was never interested in the soundtrack of any movie/ series. Generally the soundtracks are well matched to the works and very, very seldom was I annoyed or impressed with a soundtrack. So since the soundtrack in this series didn't make any impression on me, I suppose it was good. I scored it only 9 for this reason exactly.
Rewatch Value --
I had to score it 1 because otherwise I couldn't submit my review. Seems that's mandatory. But in reality I cannot score this one because I never rewatch a movie/ series irrespective of how much I liked it. I suppose it's something that has to do with my psychology or philosophy of life: since it's in the past, let it be in the past. Why dwell on it? However, I did rewatch 2 movies in this life of mine. :)))))) Hollywood movies.
Overall - 10
Yes, it's a good work and it's worth your time.
