It would've taken guts to remake one of the most acclaimed Japanese films of all time (1962's Harakiri), but then again, no one could accuse Takashi Miike of being a gutless filmmaker. I was curious to see this because some of Miike's best films are remakes or updates of stories that have already been adapted to film (like 13 Assassins and Graveyard of Honour).
This remake really follows the original perhaps a little too closely. I think it's just a few minutes shorter, and I can really only think of one scene that was in the original that wasn't in this. Visually, it replicates Masaki Kobayashi's style really well, but maybe part of me was hoping that Takashi Miike would do something a little more out-there or unexpected. Instead, he chose to be reverent to the original, but then again, it is a classic film that deserves reverence.
There's one infamous scene from the original that feels even harder to watch here, and I think the climax shakes things up a little too, to mixed effect (the final fight is fairly different). Otherwise, the story and all the characters are near-identical, and anyone familiar with the 1962 version is unlikely to find too many surprises here.
It's strange to try and review this, because it is a high-quality film... yet it's based on a high-quality classic that still holds up extremely well, so I'm not entirely sure what the rationale was behind this. For those who want to see a more modern-looking version of Harakiri in colour instead of black and white, this is very well-made and watchable, but I feel like the original is still more worthy of being watched first, for anyone unfamiliar with either film.
