Usual problems listed were:
> Unnecessarily padding out the film with filler that fucked with the pacing.
> Expanding roles for characters that were tolerably fine in small doses but not for extended periods of time (e.g. Scuttle).
> Changing the events to the point it completely changes the story into not making sense anymore (e.g. Triton being flat out killed and Ariel singlehandedly defeating Ursala means Triton shouldn't change his mind about humans after he is resurrected. In the original animation, Triton is just stripped of his powers and can personally witness Prince Eric's bravery which leads to him realising humans can be good, him dropping his prejudice and him respecting Ariel's choice).
> Changing classic, iconic songs for the worse.
> Adding weak or flat out garbage new songs (e.g. Scuttlebutt).
> CGI characters that are in the uncanny valley category.
> Weak visuals.
> Questionable acting/singing and questionable choices of actor (e.g. Awkwafina in general and getting the likes of Jonah Hauer-King to play Prince Eric when Eric now has a song and Jonah can't sing good).
In short, it was another low effort, piss weak, live action remake cash grab from Disney for an animated film that never needed a remake to begin with.
