Well, I was hoping that the Demon Slayer movie's success in limited release would lead to anime movies getting a wide release, but this release being limited probably means that anime movies will never have a wide release ever again. It's box office appears nowhere near as impressive as Demon Slayer's as it made only $6 million, hardly mainstream box office numbers. Being manga canon probably led to Demon Slayer being that lightning in a bottle that might not be able to be recaptured. Well, okay, turn of the century era Pokemon is still by far the most anime America's ever had and its box office record is still untouchable.

Not sure what the expectations are but I will note that in places like Variety and The Hollywood Reporter, they were surprised the movie made even that much.
