Another called the movie 'solid' and added, "#DemonSlayerInfinityCastle to me while solid proved my biggest worries to be correct. This wasn’t really a movie. It was an entire season of anime crammed into 2.5 hours and to me it just didn’t work. The pacing is all over the place and it hurt the experience. It’s solid overall."

A fan was speechless after watching Demon Slayer and wrote, "Just got back from seeing the new Demon Slayer movie. I knew some stuff going into it, but it was honestly great. The fights were great, the backstory with Akaza was really moving and emotional as well as the Shinobu stuff. Can't wait for the next one! #DemonSlayerInfinityCastle"

"This is called as absolute Cinema. An out-and-out pure cinematic experience don't even dare to miss in Big Screen," a movie buff wrote.

Another fan detailed, "#DemonSlayerInfinityCastle completed watching the show its the finest experience you get in big screen especially watching in Indian single screen and this movie felt more  like Akaza’s story."
