So, here's my primary issue...Le Sserafim's story, as a whole, is generally similar to that of most other KPop girl groups. Which begs the question...why make a documentary about them? In truth, I think they would have done better if they had just told their story as-is and kept Kim Garam in the story. Instead, we end up with an edited history where she seemingly never existed. To be fair, if Garam was kept in, the entire focus on the documentary would have had to been about her and her drama. But nonetheless, that story IS a part of who Le Sserafim are.
The editors did a remarkable job of pulling together so much footage and shots where they were able to crop Garam out of the frame. It's only if you look for her, that you start to notice the oddities...shots framed weirdly off center or where the focal point is right on the edge and strange cuts from Interviews that seemingly served no purpose. The editors had to reframe group shots in order to create images where Garam was not visible. They weren't perfect...there are brief seconds where an errant hand or leg appears in the shot belying the existence of the sixth member.
The fourth episode in particular is especially troubling...they must have either re-shot some of this footage or else, someone spent a lot of time digitally removing Kim Garam from the images.

In the end, for me, I got more enjoyment from this documentary by playing the game of "Where's Garam?" Rather than watching the story of Le Sserafim's debut.
