art and animation weren't 'anime movie quality' but almost as good as TV seasons 1 & 2... there were a few sketchy places like... really REALLY long shots of 'main cast of characters' that were just 'vaguely' drawn and colored so you could 'kinda sorta' tell who was on-screen... but those shots were mostly cinematic sprawling "environmental richness of the background and foreground artists' skills" shots.
the story wasn't bad. ghmm... it wasn't as badly written as 'Rimuru-sensei special OAD episodes' at the Academy with the isekai kids were written. but it was ... ahh... not up to par with the ending half of S2 P2 ... Walpurgis and the War Against Clayman etc. so that will give you a bit of a benchmark for the movie's story in context with the rest of the franchise.
sound? not bad! :D the theater i was in had one issue. the music tracks were only playing from 1 or 2 speakers i could hear out of my right ear near the screen. so, no stereo surround sound music. but the rest of the audio: SFX, English dub actors etc. were stupendous! once more, the Funi guys (i stayed for the English credits at the end. Mr. Sabat was the boss and they recorded everybody at his OkraTron 5,000 studios in Texas) were excellent! :D
if you can, get your butt in a seat and watch this movie! if you can't, my condolences and i hope you get to watch it online/on-disk/some other way.
