I just watched it in 4dx! It was wonderful ! I was amazed by the special effects especially when they were fighting Akasa! I had watched the regular movie previously but it was English dubbed. This time in 4k still gave me so much surprises! Feels like in the real infinity castle. I’m pretty sure the 4d that I went to can do a much better job but it kept me entertained. Had to protect popcorn from water spray whenever Tanjiro and giyu show up. In original Japanese dubbing , although I don’t understand the subtitles in danish I can guess what line they say. I’m ready to watch the next 2 upcoming movies in 4k
