The problem with Spongebob You're Fired is that they tried to make an epic special out of a decidedly weak premise. Don't get me wrong -- some ideas in the episode were certainly good, but the basic plot is essentially this: "Mr. Krabs fires Spongebob to save a penny." Already, it's a weak idea. A recycled, already overused gag has been stretched to somehow fill 22 minutes and naturally, the episode falls apart at the seams.
If they were going to stick to the idea of Mr. Krabs firing Spongebob, first off, it should've been for a more original reason. There were so many fresh ideas that could've been used that would've given a rehashed idea some oomph. Why should Mr. Krabs fire Spongebob? Rather than leaning on the "because he's stupid and cheap lol" crutch that the writers have been unfortunately been doing for several seasons, they could've gone with other, more logical reasons that would have provided for more introspective moments on Spongebob's end. How about because machines can make patties well, if not better, to reflect on the current trend of machines replacing people? How about because there's a frycook in town who has Spongebob's talent but is not nearly as annoying? Then they could've done that rivalry storyline that they were planning for Band Geeks. Note: I don't consider Frycook Jim a rival because it's not as if he was ever going to return to the Krusty Krab and take back Spongebob's job.
Secondly, the episode was supposed to show Spongebob's downward spiral and how he deals with not having a job. Here's the problem: rather than giving Spongebob the opportunity to try different things (which should've been a no-brainer), the writers decided to simply hammer home the gag that all Spongebob can do is make patties. What's even worse is they literally repeat this gag for a bulk of the episode. We get 75% Spongebob making patties by mistake and 25% Spongebob crying about being fired. Neither are entertaining to watch, because they're not creative in the slightest, repetitive and have been done in earlier episodes.
The special could've tackled Spongebob's journey into the realm of unemployment in a hundred different ways. He could've gotten a completely different job and struggled with it, having to accept the reality that not all jobs are as easy and that he isn't actually good at everything. On the other hand, he could've discovered a new talent. One of the only other times we've seen Spongebob do something completely different is when he became mayor and that barely counts as he had amnesia, so he wasn't even himself that time. When it comes down to it, the special should've been about Spongebob making important choices.
While being fired can open your life up to unlimited opportunities and choices, what the special ends up emphasizing is that Spongebob does all of those things because he has no other choice. We don't really see him decide anything, rather we are exposed to Spongebob on autopilot -- the kind of Spongebob that makes Krabby Patties and is bossed around. Spongebob barely gets to decide anything in the episode. He is forced out of his job, forced into doing things his best friend likes, and he ends up patty-flipping without even doing it on purpose. Plus, he's even kidnapped. So rather than Spongebob deciding to do anything, it's as if everything is thrust upon him and we have to watch 22 minutes of him being dragged around. Ultimately, it's not even his choice to go back to the Krusty Krab. Nope, it's Squidward's!
Squidward saving Spongebob, while memorable (and thus being one of the better aspects of the episode), feels wrong and rather jarring. Here's why: it happens during the climax of the episode. It happens when all the mascots are fighting over Spongebob, and it's his special, so it's supposed to be his shining moment. The entire episode is supposed to have led up to this instance wherein Spongebob finally proves his worth to himself, to the Krusty Krab, to the viewer, etc. Instead, we get a strange melee of mascots who realized off-screen that Spongebob was valuable (sort of), and they fight over him, and he literally lies limply in their arms until Squidward arrives.
So the hero of the episode is... Squidward? But... Why? Apparently, just as the mascots realized off-screen that Spongebob was valuable, so did Squidward. But the main problem is that up to this point, Squidward had utterly no role in the story. The episode wasn't supposed to be about Squidward realizing Spongebob is important. That theme is reserved for Squidward-centric episodes, which follow Squidward's thought process in ways that eventually prove satisfying to the viewer in the end because Squidward's character develops and he comes to that realization during the climax. But because this episode didn't focus on Squidward at all, him coming to the rescue just seems nonsensical, and there is no pay-off. "I hate the smell of Krabby Patties more" is a lazy excuse for a twist. Plus, the ep's supposed to be about Spongebob realizing his own importance and building his self-worth. So in the end, it's like this one episode stitched to the ending of another. Squidward kicking butt epically to get Spongebob back would've been a great conclusion to an episode centering on the Squidbob relationship. But instead it's tacked on to Spongebob's special. Spongebob is robbed off his shining moment, and Squidward is robbed of some great build-up.
And of course, Mr. Krabs gets away scott free.
In summation: an episode that was supposed to open doors for interesting, original ideas ended being formulaic and lazy. It didn't irritate me like Atlantis Squarepantis and Truth or Square but it was disappointing, especially compared to Hello Bikini Bottom (wherein the climax was pulled off perfectly) or even Frozen Face Off.
