I love Spinels character (despite the fact that this is like the third time I had to change a gemsona because a new gem was introduced and completely was not the same as my gemsona hahaha) and how cartoony she is. Eyes, gloves, pigtails, shoes, ect... I loved her movements, expressions, squeaky shoes and attitude, both as the villain and when she reverted/also in the flashback. I 100% do not blame Spinel for lashing out because when you really think about it, it is SO messed up what Pink did. Yes Pink is a brat and she's bad, but just r e a l l y think about what she did.
Spinel was created FOR Pink for entertainment to keep Pink occupied. However Pink still wanted a colony, she's still acting as a stubborn child. We can see she starts getting annoyed with Spinel but Spinel is too persistent to let up, because she can't, she was made for that. Pink tries to leave Spinel while Spinel clings on to her. Seeing she won't let go and leave her alone, Pink uses Spinels purpose of entertainment and fun against her. She tricks Spinel into playing the stand still game, then wraps IN FRONT OF SPINELS FACE, back turned so she can't see her. Honestly it would have been more messed up had Pink stared at her as she warped away. Poor Spinel doesn't deviate from her purpose until the transmission featuring Steven 6,000 year later. I mean I honestly expected Spinel to become corrupted a few times in the movie.
However there are some inconsistencies.
Where did Spinel get the injector? Why does she know how to control it? Where did she gets the scythe from? How did she get OFF of the garden? Also, Spinel seems pretty well to in terms of fighting. She knows that if she makes body parts bigger, she can cause more damage, and that she can use her own body as a weapon of sorts. She seems strong, maybe not super strong as some of the other gems, but she does keep her own in a fight for a good amount of time. Why would a jester-y gem need to be strong? If her sole purpose is entertainment, she easily could have been made weak, like typical Pearls or lower level gems. Unlike our Pearl who became stronger, Spinel wouldn't have had any sort of training to become stronger.
That aside, I do like Steg, he seems really cool. The Diamonds, eh, I feel like they're now a gag of sorts, maybe uts because they recently changed and we havent seen them in this new personality but still idk. Overall I did really enjoy the movie, so much so that I have a few WIP sketch ideas for Spinel, because I love her cartoony animated self so much.
