So I just watched the Season 5 episode "Waiting," and that's actually not a terrible episode. I even found myself laughing out loud a few times. Like when Patrick breaks the toy and Spongebob is trying to act all calm, or when they're crying and Spongebob's trying to tell Squidward what happened. ("And then my toy and then YOU and then SNAP and then this!!!)
So a couple of reasons why I think this episode might be so good...
1. The story was actually written 3 years before the episode came out. There was a Spongebob book called "Special Delivery" that was basically the exact same story.
2. It's only a 6-minute episode, so they don't have to try to fill space with stupid lines or stuff like that.
There's also a few parts I didn't like, like when Spongebob is being a jerk to all his friends. (But I guess that's kinda the point.) I would probably give it 4 stars.
