I've kept this review absolutely spoiler free because this is a movie which would completely lose any charm it has if the viewer is spoiled. Although, I personally found the poster of the movie and the arrangement of main roles in the cast itself to be a very huge spoiler.

The movie focusses on five girls at a literature club meeting, who take the podium one by one to read a short story presenting their view on the death of Shiraishi Itsumi, the queen bee of Seibo Maria Girls School. In each story the girls tell us how the kind Shiraishi Itsumi invited them to the elusive literature club, and each blames a different member for her death–mind you, this one i found quite interesting, how neither of the four think Itsumi suicided.

This a three tier story, the first being the account by the girls. Next is a message from the dead Shiraishi Itsumi herself and it reveals certain surprising details. By the end of it, we wonder is Itsumi really dead? That's where the last part of the movie comes in.

The real crimes and motivations of the girls are unexpected and quite dark considering the character we've been presented earlier–mind you, presented by they themselves. Darker is the story of Itsumi, who hides a viciousness behind that beatific smile. Darkest and craziest is the character who has been absolutely blameless. Although I could fairly predict which direction this was headed and who was lying, it would be wrong to call “Girls in the Dark” predictable.

For a thriller, it is not exactly gripping, but you somehow want to see how it ends you know? It is completely a psychological story which utilises the unreliable narration and the story will elude you till the very end, not because it's a particularly good plot twist, but because they drag it till the end. Instead of four girls, they should've kept to three because the story of the third girl Diane is just so out of place (maybe they just needed her to plant the lily flowers from France?) and makes it drag even more.

The motivations of the characters were not entertaining at all, and Itsumi herself was the most confusing one. There was no explanation for why she did what she did when she would've been much better off otherwise. The exposition of the villain is particularly ineffective, the ending was dull (and yes, after watching ten japanese productions, it's really not that hard to predict what was in that soup). Final takeaway: inconsistent storytelling which tried too hard.
