Being a big fan of the Japanese originals as well as the American remakes, I'm always in for more of this franchise it seems. That being said, I'll be the first to admit that this movie is extremely far removed from its source material. Both the books and the movies. It is just completely bonkers, in a way that only a Japanese movie can be, being such a bizarre mix of a seriously attempted plot and obviously ridiculous things, that you constantly keep wondering what you're actually looking at. If you're in the right mood, that can be very entertaining.
This movie is many things. Silly, bizarre, creative, over the top, but never boring. It takes the basic concept of Sadako and that's about it. Yes, there is a cursed video, but gone is the 7 days requirement and all the suspense it brings. Gone is her backstory as well. This Sadako doesn't follow many rules, and has as many faces and forms as all the other movies in the franchise combined. Some of them were so crazy I just had to respect the creativity of it. I mean, wow. It's a lot. Most of it wasn't actually scary, but certainly memorable.
This movie really makes me see Sadako (2019) in a different light. I think the original director returned just to remind people that Sadako 3D is not what the franchise is about. 2019 had some silly aspects, but Sadako 3D makes it look almost gritty and realistic with its utter ridiculousness, almost like an attempt at 'return to form'. It shows just how far a franchise can derail if it runs long enough.
If you want a serious suspenseful horror film like the original Ringu, nothing to see here. Me personally, I'm used to seeing long running franchises go completely off the rails (Alien and Godzilla come to mind), so seeing an interation of Sadako this crazy isn't all that surprising. Go in with an open mind, and you might have fun with it.
