Yeah too true, I feel i this movie actually has a decent budget we may get some surprising good fight scenes out of this. I felt felt with this series at least when they actually had the budget and put the effort into it, the choregraphy was surprisingly good in the.
Budget probably has little to do with it. I doubt Crimson Moon is particularly cheaper to make given the staff attached, they're just doing a shitty job. Remember that whether or not we end up liking something or whether it has great action direction in it or not usually has more to do with the talent and taste of the director and the people in charge of the fights. You don't get paid more just because you did a nice fight!
What is more important is that the movie has the same core staff that made the first anime, so hopefully they also reserved all the animators who did the major fights in the series for the movie ahead of time. Sung Hoo Park, Takahiro Shikama, and Takafumi Hori are the animators who had a big influence on how certain key episodes of the show turned out animation-wise, and the episodes which the director Yuichiro Hayashi storyboarded himself were all on point even without great animators working on them, so if the same people are on board for the movie, it should be pretty great.
