Any movie doesn't need sequel at all, because some of the endings are happy and it doesn't need to be continue
So here is mine:
The croods
The croods is first movie that doesn't need another sequel at all after new ages, because it ended well with happy ending and tbh when i heard that they going to make the third sequel, i wasn't amused tbh at all, because it's milking the franchise and it's just felt like cashgrabs
Shrek
When i heard shrek 5 is announced, i was not okay with it, because at first around late 2010s i wanted to see shrek 5 so that what happended to the story after 4 and my mind was changed when i realized not all of movie gets sequel, also if shrek 5 is the final movie of the franchise, i would be glad that it's over but if not, then dreamworks might milking the franchise again
Trolls
Trolls needs to stay as duology movie instead of trilogy, because i felt like that band together felt like it's different movie, because of the main villains that looks humanoid, because i didn't expect trolls to have third sequel, because i was thinking that the movie is over after the world tour but then i was wrong about it
Kung fu panda
After seeing alot of people hating 4th sequel because the furious five didn't have voice at all when they appeared in credits, so i suppose that kung fu panda doesn't need to be continued on more sequel, because kung fu panda 3 is true final movie to the franchise and i know that dreamworks would continued the franchise until 6th sequel, which i hoped it may be true in the future, because i don't wanted dreamworks to butchered the franchise tbh
The boss baby
I heard that dreamworks is gonna make third sequel to the movie and tbh i felt like it needs to be stopped at second, because first, the first movie was terrible and it was probably flopped tbh, also about the sequel??, well idk but i think it's kinda great because we went timeskip on several years gap where we see tim and theodore being adult man, and i felt like that dreamworks needs to stopped focused on sequel to their movie that had happy ending, unless if the ending on one of them is cliffhanger, im fine with that
