said. Rebecca has really good writing, in the later seasons the best out of all characters came when she actually sat down and ran shit.
The issue is that she was too soft and wanted artistic freedom for all the writers, she stated that there's many episodes she wanted that weren't made, like Amethyst backstory, but that makes me question...
Why did we have like 8 episodes with Ronaldo fucking around instead of actual important plotpoints and character development on the gems and their universe? I genuinely believe that some of the staff felt more comfortable/wanted to write a more slice of life with some bland comedy and Rebecca just let them go with it.
I don't know, her stuff individually looked through a bubble is fucking great, I really like her art outside of SU, and her writing and animation style too, something must have gone wrong behind the scenes for all of it to go crashing like this after the second season.
