The series clearly has to end, but there may be remedies to quell us Simpsonites from burning down fox.
How could they you ask?
By rebooting the entire series, hitting a theoretical reset button on the continuity. They could remake old episodes, and add new ones. Removing such previously established traits and such (IE Lisa as a vegetarian) and returning the show to its roots, while adding modern pop culture and settings.
Good idea or no?
