The drama was made to feel like an anime. And as a result, some situations (actually, most of them) were overacted. On the other hand, huge credits have to be given to the actors and actresses for their performances. Some of the characters were really cute and deadly at the same time, but likable overall. Some other, however, were simply annoying (see the last girl with the russian roulette themed bet). Plus, even though the cases-games were enjoyable and entertaining, the drama was left with a wide open ending. So, six out of ten, because of the ending (could have been handled better, even if there is a second season-movie on works).
