Completely shatters the perception of an entire genre, and does so while making perhaps the most flawless use of a musical score I have encountered in any anime.
Intricate plot disguised as complete chaos, then thrown at you in a mind twisting flurry of seemingly unrelated events where every answer you get generates more questions than you had before.
Overwhelming sadness and happiness at the same time.
Storytelling epic. Managed to have a large scale plot while avoiding the feeling of either being overly rediculous or tedius.
This one is here because of my personal affinity for the time period leading up to WWII. It isnt a masterpiece by any means, but I enjoyed it and was so impressed by how inexplicably satisfying the ending was that I had to include it on this list.
Probably the best thing out there in the "survival game" genre, although lumping it directly into a trope would do this show injustice. Refreshingly mature.
Rips apart your soul while constantly beating you with questions of morality, and manages to do so while still being incredibly enjoyable.
Just according to keikaku. While this anime isnt exactly the most consistantly brilliant thing, the best parts of it are so brilliantly crafted that they make up for the somewhat lazier plot points.
Somehow manages to one story to keep the other exactly on the line between emotionally charged and ludicrous. Impressively, neither story comes across as secondary or inferior to the other.
