Frozen Fever

What's the point of this? It's not long enough to have any kind of real story so you wind up with an unnecessary short that just serves as a reminder that there was this movie a couple of years ago that had these characters people liked. I mean the whole thing is basically one song stretched over a thin plot about a birthday party for Anna. That's it. It doesn't feel like they had this amazing idea for a short in mind but that they just wanted to keep the Frozen brand alive while they worked on a feature-length sequel. Maybe I'm wrong about the motivation but the whole thing just seems pointless beyond the commercial reasons. Look, I'm not saying it's a bad cartoon. It's fine for what it is but it really makes you appreciate the animated theatrical shorts from decades ago when people put effort into crafting a quality cartoon with a limited running time.
