- Alternate Character Interpretation: Marion's inner thoughts as he mourns Claude, especially in the anime... Do they imply that, had Claude's Love Confession not been as fatally anguished as it was, he would've returned his feelings? Or is he simply and very understandably high on the horrible guilt he feels over Claude's death?
- Awesome Music: The music for the OAVs, by Kentaro Haneda, is lovely.
- Narm Charm: It's melodramatic, rushed, a bit ridiculous at times by modern standards, and that's one of its charms.
- Le Film Artistique: The film seems to be made with this technique, with its solid drama represented by its music and artwork shifting to match the various moods the characters (mainly Marion) go through.
- Values Dissonance: The series is set in the France of 1890-1900 and was released in 1975, so of course it has this. i.e., the deal with the teenaged Marion having his first time with the adult Sara was as much akin to Sex as Rite-of-Passage (in-story, Jacques and Lind seem to be more concerned with Marion getting potentially kicked out of school when they find out [at least at first]), but in modern times it's seen as far creepier and full of Questionable Consent. (Even when Sara does tell Marion that she won't do anything that he doesn't want her to.)
- The Woobie: Everyone has woobie moments here but Ledania, Claude and Marion take the cake as the world falls apart around them and neither really knows what to do regarding that.
