You know what pisses me off about EQG?
This is "The human world", only with pony characters in it. AU human versions of the characters.
Who knows how their lives have been changed by the lack of magic? Not us, because Hasbro isn't interested in selling us a spinoff. EQG is just another toyline to this company, like Spy Outfit Barbie. But what they've got here is a chance to truly expand MLP's lore and write what could be an entertaining show! Come on, who wouldn't want a show about Sunset helping her friend of the week with problems while some magical Todd and the Book of Pure Evil bullshit happens and she investigates that too.
I hated Sunset in the first movie, but the second redeemed her, and the entire EQG concept.
So it pisses me off that the concept got squandered so badly after this.
Sunset is kind, mature, empathetic, and a good candidate for protagonist.
But she wants to hand the main character role over to Sci-Twi, who everypony sees as an inferior version of the real Twilight. They're all "Just accept and embrace the magic and be like the real Twilight", while ignoring that the darkness within SciTwi is something the real Twilight (Probably?) never had to deal with.
Sunset wants Scitwi to be like Twilight and become the new main character.
Sunset Shimmer is a good protagonist. Sci-Twi could be a good protagonist after a lot of character development, but she's better suited to a support role. Everything that makes SciTwi different from the real deal is something that makes her a worse protag than the real deal, so you can't make Scitwi more like Twilight without erasing her individuality.
The writers aren't allowed to address this, apparently, so the two characters are stuck in an infinite loop. Shimmer wants Twilight to be like Sparkle and overcome her darkness, SciTwi doesn't want to go anywhere near her darkness and isn't ready to overcome it, but neither wants to say anything about this on-air because they're "Just kid's show characters".
It's an infinite loop that could easily be broken by a single emotionally-resonant scene.
The writers need to do a scene where SciTwi's darkness mocks Scitwi and is all "Your friends don't love you. They love the alternate-universe horse version of you, and wish you were more like her!" for a while.
Then some fucking plot bullshit happens, they're fighting some loser who got cursed by an evil magic book, it doesn't matter.
But at the big emotional bit, Scitwi goes "That is it! I'm not 'The sciencey Twilight', I am Twilight Sparkle! I am me! Nopony else!" and then she goes inside her head and faces her shadow and gets a new Princess Of Science form that's got tron lines on her pointy wings and the power to create tech Generator Rex style or some bullshit. Then she defeats the bad guy her own way, with laser beams and explosions and "I deduced that your super hard skin is made of carbon so I made it into pencil lead lol" alchemy shit.
