The Ringu Collection

I've read Koji Suzuki's original Ringu (1991) novel in translation. It's good, but the concept around which the story revolves works better as visual media. Yes, you can take that as meaning the film is better than the book if you want. However, you then have to ask: which film? It was adapted multiple times over a short number of years, some of which spawned sequels, forcing you to be aware of the running order. My advice would be to begin with what I consider the most successful trilogy: numbers 02, 04, and 06 in the list below, in that same order. If you're still intrigued after that, then check out the others.
