Infinity castle arc will have fights between 5 main cast, 7 hashiras + npc slayers + others vs 5 Uppermoons + Muzan himself. This arc will have 10X better fights with 10X better animation. This arc will break theatres record and anime sites and will be trending for months.
30:59 I think that this will be similar to Mugen Train which started exactly after the end of Season 1 Ep 26, the other films like Entertainment District and to the Hashira Training are compilation films Although, I too will pay just to watch that last episode in theaters with movie screen and audio
Believe me Movie 1 of the castle arc is 100X better than mugen train with 10X better animation... Also watch in the highest quality because this will be one time life experience( highest quality means 4D IMAX theatres)
