Making Returns a sequel to a 20+ year old movie in the first place was a terrible idea that would've weighed down the franchise even if Returns been successful.Not to mention the obvious that not rebooting it would have meant adding more years on top of that while dragging the backstory of all the previous movies. A reboot was the obvious choice if they weren't going to make Superman 50 years older than everyone else.
If I struggled to the end of my determination, to the end of my way of life with my followers, if the result is ruin, then this ruin is inevitable. Grieve. Shed tears. But you cannot regret.
