I honestly watch it just because King is adorable. If the story gets good that's a bonus but so far it's kinda boring. I hope it'll improve when they actually get to the magic school stuff because so far Luz has learned two fucking spells and done a whole lot of dicking around doing stuff she could've done in the normal world (Like the writing competition. King was great in it but what was the point?)
I'm hoping it'll end up like star vs but better. Star vs. sucked until they left earth and kept it in Mewni, so as long as they don't ruin it with pointless shipping it'll be fine.
