The story could have been better managed at the level of the script, because, althoug the plot is interesting, it is saddled by a not so good music score, an excessive show of sentimentalism, characters that repeat themselves and do not grow enough during much of the series, far-fetched scenarios, such as being in a huge forest and not seeing either insects or animals around (only a bird appears in a moment). All of these add to major inconsistencies in the last part of the story such as: 1) Two wagons dissappear in the Tokyo Subway in 2023, and one of them reappear in 2026, few months before an impending catastrophe that the passengers tell everybody about given the facts that they have observed in the future, in 2060. Does it make sense that it is with the police authority that the passengers talk about it, and not with the scientific and major state authorities?, 2) Does it make sense that the police can not accept the passengers´s story, even though the police itself can not explain the obvious phenomenon of time travel that it has before its eyes? 3) Does it make sense that the scientific authorities do not have any exchange with the passengers to try to figure out the truth involved in such an strange phenomenon? Instead of the film bearing out these things, what we have is a replay of sentimental innuendos some of the characters, leaving the story in a frustrating open ending!!!! The series is composed of 10 episodes, which is short, but it is so slow at times that I had the sensation of being watching a 16 episodes series. However, just because I am a huge fan of science fiction and fantasy, and for what the story promised without fulfilling at all its promise, I give it 3 stars.
