As the record holder for best box office performance in Japan and #1 Foreign-language film in the U.S., Mugen Train is a fantastic canon movie that sets itself as the pinnacle of what an anime movie of a series should be.
Demon Slayer is an intense shonen that proves that the genre can stay relevant. With stellar animation, music, and pacing, it lives up to its hype. Most episodes will give you full-body goosebumps, make you cry, or both.
For having the same writer, composer, and animation studio that brings us Fate/Zero and the Heaven's Feel movies, Garden of Sinners has stellar animation and music for a boring, unconvincing story.
A stress free celebration of food and how it brings people together, starring the cast of Fate/Stay Night.
Different vibe from Fate/Zero, but still good and critical to the entire Fate Franchise. A little less ensemble, a little more shonen.
