I did not watch the movie but I watched the show so I know what is happening during the arc. I remember watching the show and I loved this story arc. One of the best fight scenes in the entire show, very well written antagonists and the scary atmosphere of the forest. The animation was also near perfection especially during the boss fight. This arc had everything, from great story to entertaining action. I recommend watching the show because the movie is shorter and may not have the same effect. Still Demon Slayer is a must see for every anime fan and also a good start for people new to the genre.
