I find it hilarious the Planes franchise was always meant to be a DTV series, and I wouldn't mind it as something lower scale like that. Personally, I'd think that Planes would be far better as a preschool TV series, where it would have at least held some relevance and probably would have at least been cute instead of obnoxious. But the thing was never meant to be released theatrically, but someone said "hey, why not" and gave the first movie an August release where somehow it made money and the first film was actually profitable, but not nearly in a way a big Pixar film would be, but it was relatively lower a budget than a standard Pixar film. The second film was essentially released because The Good Dinosaur ran into production problems. Didn't do nearly as good and only made more money than MMW because it was released in more international territories. Then the merchandise sat on shelves before Disney actually got the hint that it wasn't the big toyetic masterpiece they thought it would be.
Cars, I do understand and at least the films and shorts have a charm to them. The first movie's die cast toys were impossible to keep on shelves (I actually liked the film to want some, but couldn't find them), so keeping that franchise up makes sense. Especially since they couldn't give Ratatouille merchandise away. You know, cuz kids love movies that are about French Cuisine jokes and lectures on criticism (but adults do). Now I actually liked the Cars movies, both of them, because I didn't expect much out of either. The second film's plot always seemed like a Saturday Morning cartoon spinoff episode, but I give them credit for trying to get it to work. Plus at least it was visually stunning with all the international architecture.
It seems like Key and Peele's standard absurdist humor, and I really would like to see it myself, but it opens opposite Ratchet and Clank, so I'm conflicted.
