Filmed and released at the same time as it's predecessor "Ringu" (or "Ring", which inspired the hit American remake "The Ring"), "Rasen" (or "Spiral") is an ambitious idea. The theory behind releasing both "Ringu" and this sequel at the same time was that it would increase profits, as "Ringu" was already a successful book series and television series. However, while the 1998 release "Ringu" became an international hit, this sequel didn't sit well with people, as it is of a different tone and altogether different genre, and it wasn't as big a hit. Hence, it became the ignored, "forgotten" sequel, and was overshadowed by another sequel "Ringu 2", which was released a year later, that eliminated "Rasen" from the series continuity. (Basically, "Rasen" is to "Ringu" what "Highlander 2" is to "Highlander"- a forgotten, non-canon sequel that people ignore)
However, as the film was still made, and is easily obtainable (even in the US, where it is included with all three of the other "Ringu" films in a boxed set), I feel I should give my take, as a fan of the original film.
"Rasen" is actually not a "bad" movie, but I will say, as a sequel, it is quite misguided. I hear it follows the original novels more closely, which had more of a Sci-Fi flair to them. But as "Ringu" was changed into more-or-less a standard ghost story, this sequel's focus on the science of it was too awkward for many.
It begins soon after "Ringu"- a pathologist named Ando is called into work to perform an autopsy on Ryugi, whom as you will recall was killed in the first movie. However, during the autopsy, strange things begin to happen, and Ando is haunted by various phenomena. Eventually, he hears about the cursed video tape, and decides to watch it and solve the mystery of the vengeful being Sadako himself, with the help of Ryugi's former assistant Mai.
The film delves deep into science-fiction territory, with constant talk of viruses, cloning, etc. And without spoiling anything, the final act is very much a cautionary tale about science gone out of control. Which is why it conflicts with the ghost-story established in the first film. This is not a horror movie, this is a Sci-Fi film in the vein of "The Matrix" or "Dark City", though the battles are fought with words and not fists.
But I will say to its credit that this is still a fairly interesting film. The acting is halfway decent, the direction is alright, and even though it drags, if you can get into the Sci-Fi tone, it will keep you watching until the end.
I'd say if you're a fan of the series, check it out. It's not really a strong film, but it's worth seeing. I give it an average 6 out of 10. Not as good as "Ringu" or even "Ringu 2", but not awful, either.
