The movie itself taken as a whole is actually a good movie. Very good even.
The issue is the feminism and female empowerment. Jessie takes charge in everything and Buzz is made out to be a submissive bitch. They even do a role reversal where aside from the marriage proposal (which I find great because men proposing to women is not how it ought to be. And the fact they leave this as the only male role the male does should be all anyone needs to know about proposals. Proposing is feminine. Women should be asking the man for marriage not the other way around. Getting on a knee for a woman? LMFAO), Buzz took on all the traditionally female roles in the build-up to the marriage and in the wedding.
The White girl made friends with the black girl, ofc. All the White boys/girls were "not good friends" (until the very end, so I'll give it that).
The real issue was that the female lead, Jessie, was in charge at all times and all the guys were always just following her lead in everything. She was always in control and always the dominant one with the men meek and submissive. Woody is depicted as a balding old guy with a big gut yet Jessie, who isn't any older, is depicted as youthful and strong.
This kind of messaging fucks kids up and simp parents have no clue what it's doing to their kids.
This is why franchises need definitive endings. Every time a company tries to extend beyond the natural conclusion of a franchise in order to milk more money out of it they do something ghoulish like this.
So the Black Adder approach? Kill off all the characters at the end of the each season?
I'm not familiar with Black Adder beyond vaguely recognizing the name, so I can't really sign on blindly for that. It's less a need to tie up loose ends and more a need for a cultural attitude that makes it morally pernicious to continue something beyond its time. Think that one random encounter in Skyrim with the old Orsimer or how Japan has an established norm of "if the manga artist dies, the whole thing is over"(with the notable exceptions being Berserk and Dragon Ball, much to my chagrin).
