It's a horror film that's game-inspired... but this is being explored so far that it's quite an interesting movie. There's replaying of the same game-like events to try to achieve a different goal. (Mind you, it's nowhere near Higurashi When They Cry, Re:Zero, Steins;Gate, etc.) There's Death By CGI Overkill, which looks a bit silly but is perfect for the "computer game" thing. Significant amounts of the film are shot first person (without even an in-fiction camera to explain it away), including a scene where the heroine attacks someone with a pipe that you'd swear were screen captures from a first-person computer game.

Our heroine is Haruna Tsunematsu, played by Yuri Tsunematsu, i.e. the same surname as her character. She's writing a thesis on mystery disappearances. She visits a lady called Junko Hayama (Eriko Sato) to ask about the "Kisaragi Station" urban legend and gets told one hell of a story. The film's first half or so is what happened to Hayama when her train went somewhere it shouldn't have.

Tsunematsu then goes to Kisaragi Station herself. She works out how to get there. You or I would put this in our list of Places Never To Visit, but we're not Tsunematsu.

The tone is like a horror game. We experience unexplained weird things. You'll have absolutely no idea what they are or what they do, but they're eerie and they can make people spectacularly. Those taiko drums, for instance. There's absolutely no explanation of them, but you'll know they mean trouble. Similarly, you'll soon learn to avoid the hell out of anyone saying the same dialogue over and over again. We also meet a dickhead called Shouta who carries a knife.

The differences between Hayama and Tsunematsu are startling. Whoah. Tsunmatsu's not messing around. This is a clever, interesting film, based around a nifty idea. It only needed a stronger ending. The final revelation is cool and logical, but it's basically just a twist. Personally, I'd have liked a meatier character-based conclusion. (There's also a post-credits sequence that you shouldn't miss, but it's just joining some logical dots.)

I like the cast, although this isn't a performance-driven piece. Tsunematsu I've seen in quite a few things, e.g. the live-action version of Wasteful Days of High School Girls. As for Eriko Sato, she was the first live-action Cutey Honey, although this is twenty years later and a much darker story.

This one's pretty good. I'd have loved it had it had a better ending (although its actual one is perfectly okay).
