Construction:
As most of the manga based drama, this serie rely on how much you can merge into the drama. If you allow it to take all your thinking, the feeling of constant tension, brought by the episode or two episodes long gamble, and by the hope that the main character can rise in the academy, could make it enjoyable from the beginning to the end.

But, the tension in this season is faked by non-gamble related resolutions of gambles. And the evolution of the main character is linear and too predictable.

Story:
This part of the Kakegurui story is pretty useless. The first season introduced the Kakegurui world and introduced the objective and the main character. But this season only prepares the movie. One season followed by a movie would have been more suitable.

Direction: The biggest flaw of this season is the soliloquy-like moments, in the middle of the gambles, that should help to understand the point of view of the character and increase the pressure, when release it. Because, we don't care of the gamble, we already know that the resolution won't be related to the precedent events.

Acting: Their is almost no acting related issues, because actors only have to travel from a hyper stereotyped face and voice to an other. And they do it pretty well.

Conclusion: This season is not worth your time. Skip it and directly go to the movie.
