Everything we had before, we still have and always will. Those stories are ours-- forever.
But if I learned one thing, I'll never pine for a past Legion / continuity / era again. Because DC will ruin it. They always have.
Whatever is to be next needs to be fresh and it needs to be great. First and foremost, it needs to be writing and art I'm excited to read and mesmerized by. Nothing else matters even a little if that doesn't happen.
