- Americans Hate Tingle: The Japanese weren't fond of this movie, among other things for having Rinko Kikuchi on it (she is unpopular in her country, as they consider her an upstart who got cheap fame abroad) and for being a bit of The Theme Park Version of the original legend.
- Anticlimax Boss: The huge silver samurai is built up to be a tough fight for the ronin and even walks towards them menacingly, but then he gets blown apart by a bomb thrown into the powder room.
- Awesome Music: The score by Illan Esherki was one of the few things people liked about the movie.
- Critical Backlash: Leaving expectations and prejudices aside, it is actually not difficult to find this movie not as bad as critics say: it has some amazing visuals, a beautiful soundtrack and pretty decent action value, and the actors generally do their best with what they have. However, it still does not feel entirely as the enormously expensive production it actually was, and that is what makes one understand why it fell short.
- Evil Is Sexy: Mizuki
- Foe Yay: The scenes between Mika and the witch play out like this, particularly when the witch sneaks into Mika's room at night, slithers all over her in a seductive manner, then suggests she commit suicide.
- Ham and Cheese: Rinko Kikuchi obviously has the time of her life playing the over-the-top sorceress Mizuki.
- Took the Bad Film Seriously: With the exception of Rinko Kikuchi, pretty much everyone. Even critics who dislike the film acknowledge that the cast really are trying their best with the material they've been given.
- Visual Effects of Awesome: Even people who don't like the film have admitted that the visuals are impressive and probably the only thing well used in the 200 million dollar budget. Special mention goes to the Tengu monks and the Kirin at the films beginning.
- What The Hell, Casting Agency?: Given that Asian and Asian-American actors are less prominent in Hollywood, a considerable number of Asian-American viewers were disappointed that Universal played the But Not Too Foreign trope straight by casting Keanu Reeves as Kai.
YMMV / 47 Ronin
