But that doesn't negate that they're still original ideas not based on a previous installment or franchise and still made money.
If the argument is "I'm tired of sequels" even if that means not having Toy Story 4 which will probably be a thousand times easier than Sing, then we need to acknowledge things that ARE original in the industry right now.
Free Birds, Nut Job, Escape from Planet Earth, Planet 51, Hotel Translyvania, Turbo.
A person's definition of "creative" varies, so you can't say that creativity is dead in Hollywood because someone might say Zootopia was creative the other will just shitpost with, "It's furry town, nothing creative about that".
A lot of the people who currently don't like what's in theaters right now are just very hard to please people who can't find something that suits their niche needs.
