I found out that one legitimate grievance some people have with the movie is how Ariel is the one who kills Ursula with the shipwreck instead of Eric, with their reasoning being that the original was not only Eric's defining moment, but was also the point where Triton realised that not all humans were bad.
I guess I can understand the first point (even if I disagree; Eric has plenty of other great moments in this movie), but the first point doesn't really make sense. Triton wasn't even around to see the action unfold in either version, and thus could only rely on the word of his daughter on the matter, which he explicitly does in the remake ("I wasn't alone, Eric was with me")
And I don't see how "Eric can to help me" is any less of a guard drop on Triton's prejudice than "Eric delivered the killing blow".
