What I Liked: Great soundtrack fits the mood of the movie and is dramatic when needed. Consistent and colourful animation. The children, of all characters, are expanded upon and fleshed out. Interesting interpretations of religious figures. The dynamic between Jesus and Buddha is well done, it's fun watching them bounce off each other. Gen Hoshino and Mirai Moriyama are brilliant as the Enlightened One and the Son of God.
What I Didn't: The festival section drags its feet a little. Most of the "researched" religious jokes that make the manga brilliant are absent.
Final Verdict: Saint☆Young Men is a fluffy little buddy film about Buddha and Jesus taking a vacation to Japan's capital. A quirky (and possibly offensive) concept, sure, but the movie treats both religions with respect while treating the audience to some clever humour and heartwarming interactions between the two leads. On my Favourite Anime of All Time list.
