It's not My Little Pony, this is It's Pony. This is Its Pony, first impressions.
Nickelodeon is in desperate need of more original ideas. Their last original animated show was Welcome to the Wayne, which failed and was banished to Nicktoons because Vailskibum94 said it was similar to Gravity Falls, which it wasn't. The cartoons that have premiered since then, Rise of the TMNT and The Casagrandes, while they are good, aren't original ideas since they're based on already existing properties. Spongebob has been getting better, but The Loud House went to garbage after Kings of the Con.
It's Pony is a breath of fresh air. While it doesn't have fast-pacing or a compelling story arc, it manages to tell a sweet slice-of-life story in its own gentle way.
Annie and Pony are both likable characters that work off each other pretty well. Pony stands out since he has an irrational fear of stuff like bubbles/balloons and plants, and can get pretty nosy, but Annie still loves him, and also serves as his conscience.
There's also some good comedy, like when Pony breaks the TV in "Plants!", I nearly died laughing. It's better than the "Lol random" humor in shows like RBUK, modern Fairly OddParents, or Bunsen is a Beast. It's also better than the mean-spirited, toilet humor of Alvin and the Chipmunks. This is because it's actually smart, and when the show does have toilet humor, like in "Beatrice", where Pony farts, it's kept at a minimum.
Please support the show, we need it to be a success and to get high ratings.
