I don't quite know what you're trying to say with that - the MLP movie was perfectly acceptable. The animation was fluid, the character design was enjoyable, and the story was clearly aimed at a target audience of children with a few nods here and there to the parents.
I can assure you the SU movie will be zero of these things. They will also not ever mention the villian in the main series.
Anyway, SU still can't really write a story to save their lives, and the redemption of Yellow and Blue that seems to be looming only proves that. Honestly, they're probably going to join the gems, and then... fight White Diamond, I guess?
SU feels like a story that shouldn't have touched a genocide arc. Sugar clearly just wants a feel good show, in the end, which is fine, but it means that a lot of the message is hamfisted.
The main critiques of the series are ones that can stand quite strongly, but people do laugh at people complaining about Peridot's autistic coding is funny because, well, it's funny.
And thus SU critical falls.
