I thought you didn't watch the show anymore.
Edit

utdated opinion
Anyway, I thought this episode was really good. I espicially liked the visuals in this episode, they were some of the best I've ever seen in the show so far! I also liked the general atmosphere too, and the episode also felt fun to watch too in general, not sure how to explain it very good, but I just enjoyed it. And it was cool to see an episode that wasn't way too fast-paced or zany or any of that stuff, it felt more calmed down. I hope future episodes can be calmed down like this too while still having the great strengths of Seasons 9B-11. I espicially liked the parts after The Flying Dutchman takes all of Spongebob's friends and locks them up to scare Spongebob.
However, as others have said, it did feel like it was missing something. I feel like it didn't have that much of a plot until the Flying Dutchman takes all of Spongebob's friends to scare him, and it felt all over the place (Although this isn't really that bad of a thing). And I also felt like it could've been a bit funnier.
However, I still thought it was a great episode, and I'll say it's probably a 9.5. I still like to watch these episodes a second time though, since they sometimes seem better the second time.
Also, I wonder how many people had tragic flashbacks from the intro :P
Huh, I didn't notice a banner when I watched it. I did notice it did the thing where it freezes for a few second and then cuts a few seconds ahead at one point (and I was wondering how long it would take until this happened during a new episode airing, lol), but not a banner.
