I can't understate enough just how much the song saved this episode. Kinda cute but really mediocre otherwise, but the song definitely props this one up a few notches, it was that good.
For such a stock love triangle plot there really shouldn't have been any issues... but what the heck was Sugar Belle doing accepting Feather Bangs' advances initially? It was clear she liked Big Mac from the start and that would be the endgame. I was thinking maybe we'd get a couple scenes of her looking distasteful after Feather Bangs left her after the latest advance, but nope none of that. Maybe she was really interested in both of them, but it strikes me as dumb that if she didn't like "all this nonsense" as she eventually said, she wouldn't immediately choose straightforward and honest Big Mac over flashy dumbo Feather Bangs. Really reads like the plot demanded Feather Bangs have some success, so let's write Sugar Belle with no consistency.
Looking at
Becky's IMDB, she's been working on some recent Butch Hartman stuff, including a lot of the latest season of Fairly Oddparents, which has really declined. So I can't say I'm surprised the writing wasn't that strong... we'll see what happens if she has another episode.
