The central characters indeed are pretentious and express everything 1000% more complicated that they really needed, but just like Shinta said, that's what makes this show so different. The dialogue and story still work perfectly. The characters don't fail because of that like in more average shows that try to reach beyound the author's capability. It's quite remarkable how the author still could keep this story so solid and meaningful despite all that mumbojumbo, and how it continues to sound so convincing, after its own fashion. Maybe it's because this is all about beliefs and the mind, after all, not anything more concrete than that, despite all the bloody action.
