I think your enjoyment of this episode comes down to whether you find the character of Shauna annoying or not.
I find her very annoying, and that meant this episode suffered in terms of my rating.
'The Simpsons' has done this a couple of times in its 33rd series - try to flesh out side characters who perhaps are better in smaller doses, or used just when a joke is needed. I don't think I really needed to see some if any character development where Shauna was concerned, and this combined with the pretty far-fetched premise, didn't make this one of the better 33rd series episodes for me.
It's perfectly fine, but forgettable.
