Given that there are already eight films in the Japanese series, including a crossover with Kayako from The Grudge, it seems like The Ring franchise might be getting too familiar. Considering the original director of the first two movies is back for Sadako, one could hope for something good. This film turned out to be pretty unremarkable. There wasn't anything particularly memorable about it; it didn’t bring anything fresh to the series. It’s basically just Sadako haunting a new group of people with another story attached. However, being average isn't terrible when you consider this is the ninth movie in a franchise. At this stage, looking at other long-running series, one would expect an average rating somewhere between one and three. A four out of ten is actually pretty good for where the franchise stands now. Sadako does have some genuinely tense scenes that made me look away from the screen feeling uneasy and with my heart pounding. The suspense remains a strong point in the series, and I think that’s partly because Nakata Hideo returned to direct. Combining an urban legend with a curse-ghost haunting plot is really about all it has going for it. Hideo continues to demonstrate his skill at building suspense, and honestly, it's the only reason I would consider watching this again—for those few moments he creates that get your heart racing. With an ending deserving of some kind of award for being awkward, particularly in the last couple of scenes, Sadako doesn’t really live up to what The Ring franchise has previously represented. I almost wish they'd just let Sadako rest and be at peace. Considering this ninth film is somewhat disappointing, it might be time to move on from Sadako, allow her to escape her curse, and end the series. This installment barely manages to stay afloat; a tenth one would probably collapse entirely.
