This wasn’t bad, per se, but I’m underwhelmed.
The premise is dumb but interesting at the same time. Our heroes, (non)-members of the puzzle solving club, solve puzzles with life or death stakes. The puzzles look interesting, even if the means of solving them are completely outside the audience’s hands. I feel that if you’re going to make a show about puzzles, you should at least make it possible for the audience to think about the puzzle and solve it themselves.
The biggest problem is the characters: none of them particularly interest me. It looks like our usual shounen school setting, filled with wacky hair styles. Our protagonist is full of himself. He has a violent childhood friend. The mysterious student council president is hiding something. I don’t really care about any of these people.
The way they develop the protagonist’s motivations and talents is especially pathetic. He made a childhood premise with what looks like his father to “free the puzzles.” Hilarious. Then to convince us of how smart he is, the creators have him solve a Sudoku puzzle. And everyone in the puzzle club is amazed. Seriously, guys? Is everyone at this school an idiot? It even took the person who wrote the puzzle an entire day to solve. How is that even possible?
