“It’s clear that a lot of thought and care went into the final adventure of Makoto Naegi and friends, and the results mostly speak to that effort. The story’s primary fault lies with the very nature of its new Killing Game, which doesn’t allow for the murder-mystery fun that the precious games delivered. Instead of participating in whodunit mysteries and gripping trials, the Future Foundation members end up in a battle of wits and deception that moves the plot along swiftly at the expense of the goofy mystery and bizarre intrigue that made the franchise famous. A couple of sub-plots end up petering out instead of resolving in a satisfying manner, but the main story moves along so briskly that those loose threads and dead ends are a bit easier to forgive.”
