We saw it. I don't know what my kid thought of it, but I thought it was at least better than the book. Not quite as good as the previous movies, but it had its moments.
Usually I like reading the books to him, because they skip most of the silliness and stick to the main story, but that left this novelization a bit barebones.
My main disappointment was that, for whatever reason, they replaced Brian Doyle-Murray with Mark Hamill. I was kind of looking forward to seeing him on the "big screen" again.
I don't know about the poll, I don't really watch the show. I know a lot of people say it went downhill after Hillenburg stepped down. My kid usually sees them in random order, but when we do watch them on demand, I think we're on season 4 right now.
