Todd Russell’s review published on Letterboxd:
Some of the wildest and well-done martial-arts action scenes involving knives that I've seen. This is Japanese and subtitled, so for those who get hung up on that (not me), disclaimer is here. Directed by Yûji Shimomura and starring Tak Sakaguchi (as TAK∴) Think I'm going to have to research more of this director's movies.
This reminded me a little bit of Game of Death by Bruce Lee in that it's one guy against an onslaught of bad guys, some of them more skilled than others. The Wikipedia has a review comparing it to a videogame. That's a fair comparison, as well. It's not a great movie, just OK, but for those who enjoy fighting scenes, it's recommended.
