I do applaud them for allowing the guest star, Anne Hathaway, more than just a line here or there. Not only did she have major dialogue, she also sang for the episode.
I thought I was going to totally hate this episode. The Princess was taking over the Krusty Show, then her being in love with Krusty came out of left field.
When Krusty's network feels that they need to get more girls to watch the show, they make him add a female sidekick, Princess Penelope - and Krusty falls in love with her; Mr. Burns gets rid of free donuts at the power plant, leading Homer, Lenny, and Carl to hire a headhunter to look for other employment.
