Still a 7 out of 10, because it's an original, unique, and awesome story about love and loss. Rio2096: A Story of Love & Fury is one of my most favorite films of all time, it's seductively intriguing and has such a great story.
The problem here is that The Immortal Warrior (released in 2020), states that this is an English-language sequel to Rio 2096, but actually it's not a sequel at all, it's literally just an English dubbing of the film that released in 2013.
The English dubbing isn't terrible or anything, but it certainly lacks the charm of the original film's language. There are always nuances and linguistical minutiae that seems lost when a film is re-dubbed, and in certain scenes throughout the three stories this is certainly present.
The thing is -- and the most important part about all of this -- is that....
THIS IS NOT A SEQUEL
If you were expecting a continuation of the events that happen in the last story, you're sorely mistaken.
This doesn't make the film bad, but basically it's just a redub of a great film with nothing new.
If you haven't already seen Rio 2096: A Story of Love and Fury, and you aren't fond of subtitles, then I suppose The Immortal Warrior makes sense to watch. But otherwise, it would probably be better to stick with the original 2013 film.
Just remember, this is not a sequel, it's the exact same film just in English.
