When Attack on Titan first came out, the concept of Humans vs Titans was so unique that it became an instant hit all over the world. Fans thought this Anime is so dark compared to other anime because you never knew when your favourite character gets killed.

When Marley Arc started in Manga, we came to know the point of view of other side, the warriors (who we considered the enemy) and that is where all the discussion about morales and beliefs began. 
The biggest question which divided the fandom was “Would you rather choose to save your home country or humanity?”. 
There have been several poles conducted on “Anti-Rumbling and Pro-Rumbling” and it almost always get equal votes on every social media platform. It is remarkable that how come Isayama even created these situations (intentionally?) and both sides give strong and logical arguments to defend their point.
What makes Attack on Titan so unique and great is that first it hooks you up with this fascinating story about Humans fighting Titans, than it slowly but surely drags you to this complex and twisted story where Characters have to make these hard choices and they have to live with it for the rest of their lives.
Finally some people have started to understand the point that “Nobody in this story is right or wrong, it’s just people and their choices that they make”.

Attack on Titan final season is scheduled to premiere on December 7 and produced by studio Mappa. Fans have high expectations from Mappa Studio. Previous three seasons of Attack on Titan had high quality animation by studio wit. This change in studio might have a big impact on Attack on Titan legacy will be remembered.
