"Art is intrinsically subjective, and, while some can grasp the message behind an art-piece instantly, others might need to mull over it more than once to truly appreciate its beauty. Anime is no different, as viewers often need to watch a series more than once to understand it. While there is plenty of commercial anime that can be viewed easily without having to think much about it, there exists a special batch that deals with complex subjects and requires more than one viewing for absolute appreciation. These anime might deal with a setting that lovers of the genre have come across multiple times before. However, the way these anime deal with these settings, using symbolism, allusions, psychological implications, and a warped narrative structure, is what forces viewers to think deeply about them."
