If they want to reboot the show, don't make it a season 7, make it a spin-off like Once Upon A Time in Wonderland (Except actually good). It won't feel like the same show and will feel more like how when Misty left Pokemon and they kept on replacing the female characters and eventually replaced Brock as well. Pokemon was even more milked than Winx Club and The Land Before Time, I don't want Once Upon A Time to suffer the same fate. Sure Ash and Team Rocket were always there, but they got to a point where they were exaggerated versions of themselves, got repetitive, and were pretty much unrecognizable. Regina's story feels complete because she's learned to love herself and accept herself in this world. They shouldn't beat a dead horse and just leave well-enough alone. I never thought I'd ever be upset over Once Upon A Time getting a new season but it really needed to end after season 6.

Although I do wish they had found a way to make the final battle between Regina and Emma.

I'm not caught up on the show yet but if all of these options are true, I'm kinda upset by it. They better do something amazing to make up for what they're losing.

All of them minus the Gold and the perfect way to end it ones. But again my Regina obsession is enough for me to give it a try.

Basically all of the actors who were leaving/characters being written out, but Emma was the biggest impact.
