I watched, back-to-back, in this order:
Rurouni Kenshin: The Beginning, 2021
Rurouni Kenshin: Origins, 2012
Rurouni Kenshin 2: Kyoto Inferno, 2014
Rurouni Kenshin 3: The Legend Ends, 2014
Rurouni Kenshin: The Final, 2021
I watched the first 3 ages ago, but decided to watch all of them again, in story, not release, order, which I recommend doing.

I absolutely love these films to bits. The life of the main character is a mix of almost aimless at times, tragic, enlightenment and atonement.

The fact the film about Kenshin's origins, was made 9 years after the character first appeared on screen, is amazing. The main reason being, when watched in the order I did, it is a seamless story.

Many cast members appear throughout, pieces from the earlier, film 1, are blended in so when watching the next instalment, it makes complete sense. I was honestly blown away.

Satoh Takeru is brilliant in every film. The sword fights are incredible and they must have taken all the cast involved, a huge amount of work and energy.

The pace of each film is excellent, with a balance of action, everyday life, love, friendships, fighting for a cause (sometimes blindly) and defeating not only enemies, but those taking advantage of the powerless. Some sad elements too. There is also humour and a growing camaraderie between some characters that began as enemies.

I love Himura Kenshin and how he evolves. Supporting characters are varied, some villains are pretty OTT, strong female characters and the cast in all the films is great.
Films are rarely, if ever, perfect, but these just do it for me. Firm favourites.
