I think I just figured why the self depreciating humor works so much better here than it does in the show.
When the show did it, it was essentially saying "We know exactly what you want, but we're not going to give it to you." It always said things like "We can't make it super serious like the original because it's a kids show." or "Stop getting so upset about a kids show." It said that they knew what they were doing, and said that what they were doing was perfectly right.
But that's not what they're doing here. They're showing us what's wrong, and saying "Yeah, that doesn't work. You can't expect to act like jackrabbits and say nothing but the word waffles for ten minutes and expect everything to be okay." This movie is taking itsel seriously in the best possible way it can, and I love it.
