I hate it when iconical series like MLP G4, Duck Tales or something like that get totally re-made. It means that an entire fandom which formed on an old version of a story get just thrown out by their praised studio. Not always, but it happens. Like, you know, who will I be associated with when there will be no Scootaloo?
Maybe I’m dramatizing too much, but imho it’s better when series just stop at the right moment. Like Disney did it with Gravity Falls. Don’t rape old things which already had their time to change the world. Try to make something new.
