Ditto (2022) had the main essence of the story down already. The casts were also good in portraying their roles. Especially the main lead, Yeo Jin Goo. He was able to flawlessly show the emotions needed; from falling in love, being paranoid, jealous, up to being broken. The cinematography was also brilliant. The usage of colors to differentiate timelines and create mood was perfectly executed.

The downfall of this movie was it's flow. It failed to show the relationship of the other characters to the main lead, Kim Yong. And these relationships are the backbone of the story. This is what would've make all the difference. These relationships are what'll make viewers invested to the story. Sadly, the movie focused on moving from past to present which led to very disorganized story.

As an example the past storyline:
The friendship of Kim Yong to Eun Sung. They were supposed to be best friends. But in the movie, it seemed like Eun Sung is the only one portraying best friend. Kim Yong was suddenly this overly jealous and paranoid boyfriend to Han Sol. Then his relationship with Han Sol also seemed rushed. We weren't given enough scenes to be invested in their story. We just see Kim Yong being really inlove with her, but on Han Sols part, there weren't enough scenes to staple or depict her feeling the same way. If the movie gave more light and exposure to their relationship, I think, viewers, such as I, would've felt more about their story.
