Ninjas wouldn’t usually be considered “weird” enough for a Weird Western but this is a highly-stylized movie where the ninjas can basically fly. They might as well be mythical creatures given how ridiculously they’re portrayed here.
Of course, like most movies I’ve mentioned here, this isn’t a good movie. So lower any expectations. It takes a while to get started and basically the first half of the movie is “slice of life” as the main character settles into his new life. Also, there’s something weird with the lighting where I can’t tell if the entire movie was filmed on a sound stage or if all the backgrounds are cgi (probably both).
Here’s a trailer. You can watch it on Amazon Prime, Tubi, Vudu, and Plex.
It is free with ads on Prime Video. It is also available on STARZ, presumably free (I cancelled my subscription after Black Sails ended)
