>>92854039Keep in mind that Ashi vanished due to a time paradox. That means the people behind the show decided that they wanted to employ the nastier consequences of time travel for drama, instead of simply ignoring them. But the scene they wrote didn't have much impact because it felt like a mediocre ripoff of TTGL.
It would've been possible to write something more interesting and satisfying than the lazy ending we got. I've seen random /co/ shitposters coming up with a lot of better concepts. I don't personally like all the ones in this picture, but most of them at least display more effort than the show itself.
>>92854299Shrek agreed to change his past in Shrek 4, unwittingly getting Fiona's parents killed and his own children never being born. Haruhi Suzumiya movie had the protagonist forced to pick between two alternate timelines, which meant erasing one of the timelines out of existence and rewriting his friends (as well as hurting one of them pretty badly). You mentioned JLU; that show had a pleasant future version of Vandal Savage fading into nonexistence after Superman changed the past. But that ending was satisfying because Savage was at peace with the idea of sacrificing himself for the world.
Butterfly effect has been done in a lot of works, but usually the heroes are given a happy ending, and the writers attempt to push away all the uncomfortable implications so that the audience can either ignore or forgive them. People are upset with SJ's handling of it because it's hard to ignore the fact that nobody knows what happened to the future characters.
