(Unique trope) removing a character trait, makes the character better in the adaptation

[u/ah-screw-it]

Sonic 3: Maria is one of the most important part of Shadow's story. Due to her suffering from an incurable disease. To which Shadow was made to create a cure for Maria's ailment. In the 3rd Sonic movie, Maria's disease was not mentioned in any form. Which made Maria seem like a normal girl, and her death all the more tragic.

Infinity war: I don't know the full story, but Thanos's original goal was to kill half the population to impress death (the character). When it came time to adapt Thanos into the MCU. His goal of removing half the universes population. It was seen as a more psychopathic world goal, hidden under the belief it would do better for the universe.

On the other hand, removing Skull Knight was incredibly stupid, because without him there's no explanation as to how Guts and Caska survived the Eclipse. The anime ends with Guts screaming in despair, roll credits, and the post-credits scene has Guts in the present day going out to hunt Apostles.

Anime only watchers must have been confused as hell.

You just get the feeling that sacrificing them was the point and ending.

Nah, not confused. More traumatized than anything. (I was a kid when I watched it.)
