The humour is definitely in line For Pinocchio, I’d agree (tho also it’s been a long time since I’ve seen it) and i definitely didn’t even want to touch dumbo because the reason you underlined, as for the animaniacs/picky and the brain, and all those Warner Brother products of the same vein, I Would personally give that a pass more because it’s design was supposed to be funny, they are strictly comedies, the jokes were supposed to be zany and borrow from our world, like the simpsons for example.
I think the important thing is for Disney to figure out what it wants to be/the tone it wants to set. I can’t believe they are aiming to come off as a WB cartoon unlike something like Hotel Transylvania (which also has a lot of references, which are totally hilarious and well suited to the story) but Most of Disney’s stories are about storytelling, and for me at least combined with picking celebrity actors over decent voice actors, the jokes don’t fit with the material. It’s like a cheap laugh.
You have really good points about Mulan, but just like Eddie Murphy was A very spirited voice actor, the parts that were the pop culture humour references were my least favourite as compared to his genuinely good shtick with the cricket and mulan. It’s the same with the gargoyles in Hunch back of Notre Dame (which most people I’ve talked to weren’t a big fan of). I get, these characters and their punch lines are supposed to cut the very serious moments of war/oppression and racism, but they do it very awkwardly and often not well. Although obviously you want them to be children friendly (which I believe you still can do even if the content isn’t 100% happy ending) but if you want a story to have gravitas, you shouldn't split the tone up as much. Much like the Ghibli film Spirited away Was made I think in 2000-ish It has its moments of comedy, but it’s not In itself a comedy Like animaniacs, it isn’t the place for lines that will take audiences out of the movie. Oh or avatar you get TONES of humour, but you’re not going to risk tone or world building by throwing in a 2000s pop culture reference that shouldn’t even exist in that world.(The cabbages scene is perfect for this, no one has to know anything about cabbages, it’s just funny)
I feel like that’s a lot from me, your points definitely gave me a lot to think about, but I think for the most part I’d still keep the idea there’s a time and place for pop culture humour, for the most part, it just doesn’t really belong in a totally different Fantasy world where the main focus isn’t humour And you can still get hilarious scenes without referencing back to our world. But on the other hand I don’t dislike pop culture references (again, I very much enjoyed hotel Transylvania, the simpsons and animaniacs tho I haven’t got around to watching the new one)
