for Anime only audience

@Tmdcmnr Yes, my point is that complexity does not make something good. If it is so complex that it cannot be easily understood, it is written poorly. The power systems of FMA, HxH, and JoJo are better than LOTM because you as an audience understand what is and isn't possible and can create a mental outline of everyone's capabilities even without being explicitly shown. In LOTM, they could just whip out a new spell each episode and say "This is part of a sequence you haven't seen yet" and you'd be like oh ok i guess. If you cannot create a mental architecture for someone's abilities before you see them, it's not well written.

My point was not that no series makes you sit on a mystery or incomplete information for multiple episodes. It's that good mysteries make it clear to you what it is you do not understand, and don't leave you guessing as to whether or not you should know what's happening and if you missed something and need to rewatch. In FMA, it is explicitly clear that you are not supposed to know how the philosopher's stone exists and what its limitations are. In LOTM, it is ambiguous as to whether or not the audience should know what the mist is since Klein seems to have capabilities within it that are not made clear to you, and you sit there struggling to understand what he is doing and if you should know the same things he does
