[Please note that there will be spoilers for Season 1 of Demon Slayer, but not for the movie]
It’s Thursday night in Odeon. I go to screen seven and I feel it. They haven’t been outside since before COVID, not even realising there is a lockdown. Their must is enforcing of social distancing in a way that would make Chris Whitty shed a tear of joy. These are the anime nerds.
I do of course kid the anime nerds out there. I’ll put my cards on the table here. I don’t really watch anime TV series, I don’t watch much TV at all. However, I respect it as a medium and it does some interesting things. Occasionally if it’s on, I’ll go and see it at the cinema (maybe once or twice a year) to see something different and I always judge it fairly. I had a great time with Akira while I also enjoyed Weathering With You. Needless to say Spirited Away is one of the best movies ever and I cried loads at Grave of the Fireflies. I also get a lump in my throat when Ash gets turned to stone and Pikachu cries. However, DSMT is probably the most hardcore anime film I’ve sat in, mainly due to how much it links to the series, which is available on Netflix.
Going into this film, I didn’t know a thing about Demon Slayer apart from what I learnt in a ten minute summary on IGN (which you can find here). However, I was curious about the most successful box office film ever in Japan. Therefore, while I will talk about the technical aspects universally, I will talk about the story from the perspective of not having too much information.
The important things to know from season one are:
A protagonist with a mark on his head (Let’s call him Harry Potter) comes home one day to find his family murdered by demons, apart from sister who was turned into a demon. He becomes a demon slayer, along with his friends, one is an annoying creepy loud blonde boy (Let’s call him Ron) and the other is overly excited and has a pig on his head (He can be boar-omir). They go around slaying demons and looking to kill the chief bad guy. However, there are some super demons, Premiership demons and Championship Demons. There is only one championship demon left who has super powers or something. Harry, Ron and Boaromir have been sent on a train to find the fire super dragon slayer, let’s call him Dumbledore and that’s where the film starts.
For fans of the demon slayer franchise, you’ll really enjoy this. While some of it was lost on me, there was plenty of chatter as the credits roled and it sounded excitable. I can only imagine that when the Community movie comes out, I’ll be just as excited afterwards in my Joe hair, in my Chang wig, in my Jeff wig in my bald cap. There isn’t much I can say from your perspective, but it’s fine.
However, for those who aren’t fans of Demon Slayer, it’s not as accessible. The film essentially plays out like a two hour episode of the show. Harry, Ron and Boaromir are on the train, and need to take down the higher championship demon which sends them to sleep and kill them via that. It’s basically Charlie Kauffman and they live out their ideal dreams, but need to wake up, thus some season 1 context being necessary. There are also significant story moments which will be lost on you. There isn’t really a neat beginning, middle and end. It’s like watching Harry Potter and the Goblet of Fire without seeing any of the other ones. If you’re cool with that then great. Otherwise, maybe stay away.
The animation looks nice. They clearly put a lot of effort in. As demons only come out at night, some of the earlier nicer lighting is lost, however the interior of the train looks great. The style is fun and unique, instead of what I usually complain about.

The story had a few moments I thought were great. The emotional moments, especially in Harry Potter’s dreams didn’t have the impact on my they would desire, mainly due to my lack of time invested in Mr Potter, although the climax of the dream scenes was pretty cool. There were also some moments later on where the emotion seemed disproportionate, although maybe I was missing something, I’ll wait for someone who has seen the movie to discuss with me whether it was.
The rest of it was fine. The soundtrack was fine and that, although the film’s second act wasn’t as good as its first. It pivoted seemingly out of nowhere in a different direction and it would have been nice for it to have been alluded to, although it may have been and I wouldn’t have known. I don’t want to spoil it for those who haven’t seen it, but the story essentially stops, and it becomes a whole new episode which didn’t live up to the last.
There were some quirks that bugged me. I really did not like the Ron character. He is unnecessarily creepy, and I just wanted him to die. Boaromir was mildly humorous at times, although some of it was poorly timed and took me out of the moment. However, this was my opinion and if you like the show, you won’t have an issue with it. I guess the style of the anime may be lost on me in that regard and I’m not sorry for feeling that way.
Summary
Demon Slayer: Mugen Train is essentially fan service. Those who love the series will have a great time. However, those who do not know a thing will struggle as it’s not very accessible. While it looks pretty, the film is little more than two extended episodes stuck together, albeit with some interesting moments throughout. [Grade: C+]
