It was really good, no complaints about pacing or anything. I actually enjoyed the more cinematic approach for Season 1, but I'm fine with a more simplified, closer-to-the-manga art style. I do wish they did let the colors pop a bit more during the action scenes. When they kill the Typhoon Devil the color shifts to the colors and shading of the first manga cover. I kind of wish more of the fight sequences were colored that way - I don't mind the lifelike look for the non-action scenes.
I was hoping the film would end on Denji waiting until night in the cafe, but they put it in the aftercredits. It's not a big deal, but Denji legitimately depressed because he never knew Reze tried to come back for him was the somber note I wanted them to end the movie on (before Power comes in lighten the mood at the very end).
