While I loved the vibrancy of this episode, I thought it didn't quite live up to its concept.
First off, we get too much leading up to Spongebob's creation of the bulletin board. That could've established the premise with one shot and one line but instead we get Spongebob coming up with the idea and the overly long scene with the grandma. However, the episode really does pick up once the townspeople start getting into it. One thing I noticed is that Mr. Krabs (despite the usual references to his greed) seemed to care about how well-liked the Krusty Krab is and how nasty people were becoming. My favorite part of the episode is definitely when things spiral out of control and the comments turn vicious, along with people's reactions.
Nice to see that Bubble Bass hasn't changed at all (not). He's still trying to rile people up. Squidward stands up to him this time, which is nice. I really liked his line "I'll give you a number... Of contusions!" Guess he really gained confidence after learning karate.
(Spoilers follow):
I didn't like how most of the comments could be traced back to Patrick. Sure, he meant well and he wasn't being cruel on purpose, but in my opinion, finding out who PStar7 was didn't matter as everyone was being cruel to each other. He may have inadvertently started it, but everyone propagated it. It was satisfying watching Mr. Krabs throw people out of the Krusty Krab, but as usual, the townspeople don't really learn their lesson.
Squidward's reaction to seeing a negative review of him was funny, though: "Don't you yokos know I'm working here IRONICALLY?!"
The episode peters down when we get to the stakeout scene. Apparently Squidward has a tattoo now (what?) which Mr. Krabs and Spongebob make fun of. It's another Squidbob moment but oh well, I guess that was inevitable. Mr. Krabs destroying the bulletin board seemed like a casual affair than the climax they were trying to make it be, but it was nice how he moved Patrick out of the way instead of taking his anger out on him.
Interesting note: this episode leads directly into Food Con Castaways because everyone takes up knitting in the end, which is why Squidward is knitting in the next episode. "Bring back PStar7!" was kind of random. Now I'm wondering if there's supposed to be an episode leading up to this that explains Squidward's tattoo.
