I am going through a few movies and I see Pokémon: Zoroark: Master of Illusions. Are that many colons appropriate? I am inclined to use em-dashes for the next subtitle, leading to Pokémon: Zoroark — Master of Illusions. This looks right to me, I'm happy. ...Until I go to the next movie.
What do I do here: Pokémon: The Movie: White: Victini and Zekrom? I am inclined to use an em-dash again for the first subtitle (as in, Pokémon: The Movie — White) but what about the next subtitle, another em-dash or alternate back to a colon? Or, possibly radically, another symbol altogether? Is there a suggested method?
Thanks, any thoughts are appreciated.
