The final film in the Ringu series, Ringu 0 takes us back 30 years to learn the origins of that girl in the well, who she was, and how she ended up down there.

Too bad it's not a very compelling story. Sadako (Yukie Nakama) is an actress in college -- sort of -- and she's so nuanced that she draws the ire of her fellow actors. This culminates in Sadako being beaten to death by the troupe and coming back as a ghost to get her revenge. Sounds cool, but unfortunately the film spends about 85 minutes getting to the juicy bits. So for about 20 minutes, we've got a cool little thriller on our hands -- culminating in a cool and harrowing hunt through the woods. The other 80 is nothing but padding.

Still, it's amazing that the strength of Ringu managed to milk four movies out of its simple premise. But hey, Star Trek has already managed 10 movies. Now that's scary.

Aka Ring 0, Ringu 0: Bâsudei, Ring 0: Birthday. You can get the entire Ringu set of four films in a single box set, "Anthology of Terror."
