This Japanese found footage horror anthology is only the first entry in a long (10+) series of films.

The first thing you notice is how Youtube-ready this film is. I'm not sure, but I think it might have been uploaded on that platform first. And it is well suited for something like that, being an almost context-free series of short creepy vignettes. It's only an hour long, too.

So, this first entry doesn't really impress in any way, shape or form. It's a Noroi-lookalike in a sense that it zooms in on every little uncanny detail, but given its episodic nature, sometimes that's all it has time to do before ending a segment. Some of them end very abruptly, while others get a deeper analysis, but none of them really amount to much. The effects are less than great, too.

All the criticism aside, it's OK as a time waster. I wasn't very thrilled by it, but it still kept my attention. I'm hoping the sequels will do a better job of creeping me out, though.

On a side note, Koji Shiraishi's Ura Horror is a very similar comparison, with this one being a slightly inferior version. If you enjoyed that one, you also might like this, but be prepared for rather weak English subtitles.
