It didn't skillfully address the anxieties of the age. It treated the potentially rich subject matter superficially. Lacking in suspense, the ending was unsatisfying. I expected a deeper, more engaging approach.

Acting is average, the script needs improvement. The pacing is slow and it's not a significant loss if it's not watched. It needs improvement.

A Korean drama or film that successfully tackles the subjects of technology and communication. It offers a fluid script that makes time fly by. Korean talent deserves commendation. Score: 8.
