Loved this movie but there’s a but 😀 Let’s discuss shall we – Mostly in spoiler section!


We’re entering the final battle of this series so I wont go into what this movie is about. If you’re jumping in here……go watch the series and come back in the potentially 2 year gap before part 2 of this 3 part movie trilogy. YEA! 2029 could be when this conclusion wraps up. I think a whole bunch of people will be checking out this manga in that time span. (It’s very short series) Which is insane it’ll take so long.

I’ll save my rant in the spoiler section about that last comment above.

Let’s discuss non spoiler quick and then elaborate. By the by, speaking with my wife. We are two different fans of this property which I’m sure will be a challenge for the creator to please us both in the next 2 parts….. love to hear your thoughts on that one.

What I enjoyed!

Loved the action scenes, the quality of the imagery & the epic music! The film finished & started extremely strong. I’m pumped for the second part and may even re-read the manga once more.

What I didn’t enjoy!

The move felt long due to a foot on & off the pedal / gas pacing. From memory of watching this feature. All the scenes that weren’t present within the battle / (Spoiler) were in TV quality it felt like over the quality that was being shown during the battles. It did feel off and the cut to black felt like this is where the “episode” ended before continuing.

Why there’s a rant?

Because I love this series and I thoroughly enjoyed a lot of this movie. But the elephant in the room for me personally. Nezha 2. It’s my #1 animated movie for this year. I want Demon Slayer to destroy it or at least be held on that level…… for my personally. Due to spoiler talk. It just misses it. I’d love an edited version that shortens the movie and keeps to the battles / ending. But then that’s where my wife’s & I’s experience differ.


Shall we transition!

This is the final battle. It’s a trilogy of movies to finish this franchise. If you’re watching this movie. You most likely know what you’re getting into. Or have friends / family that have clued you in so you can enjoy this movie without or with little confusion.

So with that said and before we jump into spoilers. I’m giving the Infinity Castle Demon Slayer movie a very strong great 8.5/10 which I’d love to have had been a 9. Maybe it’s a 9 and Nezha 2 a 9.5 but seriously let’s get into why.


Wrap before the spoiler talk

Appreciate you for taking the time to come by Popped for your movie “Reviews”. This is an interesting one to discuss. With it being the finale of a series rather than a stand alone movie or earlier part of a series like the first movie which felt perfect as apart of the series while also stand alone.

Lots to discuss further more within the spoiler talk that not even I mentioned. So if you’re interested. I’d love to hear from you in the comments or soon to be our specific social media pages that I’ll eventually create by year 3 of this platform haha.

Until next time though – Happy movie going everyone ❤


Spoiler Talk


The battles were freaking awesome. The music and scores could rival that of KPop Demon Hunter which are Oscar worthy. But every time the battle got going you’d be taken out of the moment to have flash backs. You’ll have a recap or moment to build up and explain how we’re going to have the ability to defeat or fight further the opponent in front of us. (Reading the manga felt very quick and maybe it works in this media) But the movie having this took me out of the experience constantly in those first 2 fights.

Now with this said, this was my personal experience. My wife loved those parts while not enjoying the backstory of the last fight which I personally loved and hope it executed in the next feature in part 2.

Which brings me to the potential 2 year gap between sequels. I read it’s to improve the quality of the film….So why did those flash backs feel like quality TV episodes rather than feel like the movie playing around it? I hope this is what they mean by improving the quality but who’s to know other than the creators.

That ending had me hyped as it lead perfectly into the second part. I’m ready for more. I’ll have to re-watch the movie once more and see if that 8.5 gets to a 9. (Sinners did it but mainly due to a couple next to me talking).

Love to hear your thoughts in the comments on your experience. The movie was epic! Let’s agree there. But did you find it long due to reasons mentioned above? Did you get taken out of the fights due to the same reasons or another? Let me know below. I’m personally hoping part 2 is like the last fight. Nezha 2 had an incredible last 40 minutes that offered so much emotion while feeling epic and connected. For those that watched it and get what I mean let me know your thoughts also on the two experiences.
