This story of the 47 loyal ronin (ronin is a Japanese word for a master-less samurai) is based on actual events that took place in 1701 and 1702--although some of the exact details are uncertain (including the actual number) . What is certain is that a feudal lord attempted to murder on of the Shogun's trusted men in one of the royal castles. As a result, the attempted murderer was ordered to commit ritual suicide and his retainers (now ronin) vowed revenge on the man almost killed. What the exact insult was is lost to history, but the tale is considered a classic and most Japanese people are very familiar with it.
It would have a very hard time giving any version of this story a 10 because there are so very many that you can't give them anything for originality. According to IMDb, on Japanese TV alone, something like a dozen different versions were made just during one decade! And, as far as movies go, there are also quite a few. I've seen the classic 1941 version and found it to be very, very different from CHUSHINGURA because it was much more nationalistic and seemed, at times, like wartime propaganda (albeit, very good propaganda) AND because the film was much more fast-moving--skipping much of the setup that you find in this remake. In other words, in 1941, the insult and the attempted murder take place very early into the film and here in 1962, it doesn't occur until about an hour into the film. In fact, while an amazingly well made film, CHUSHINGURA is perhaps too deliberately paced and could have used an edit. While I like very long films, this one just wasn't paced well enough to merit its 3-1/2 hour running time. At 2-1/2 or 3 hours, it would have played better.
As for the acting, sets and everything else about the film, it was all first-rate. The film was obviously a prestige film and as a consequence was filmed in lovely full-color. In fact, other than the pacing and ubiquity of the plot, it's a very well made and interesting film--probably even more so in Japan, where it's a beloved tale illustrating loyalty and honor.
Finally, it should be noted that although Toshirô Mifune is shown on the DVD art and all the pictures here on IMDb, his role is very small and this is definitely a film with a large ensemble cast--not a Mifune film per se. His fans might be disappointed by this and you might want to consider this before you watch.
