We will start off positive, the lead actress can sing so the song "part of your world" is pretty awesome. Melissa McCarthy crushes her role as Ursula
Now for the negative(spoilers)
While the actress can sing, her acting left a lot to be desired
The cgi in this movie looks dated and just overall sloppy. Several scenes just look off. The lighting in the movie is also not present. Is it illegal to have a wall lit movie?
They changed a few story elements that made the ending make sense. Original movie humans killed ariels mom so when Eric kills Ursula and he makes his daughter human it makes sense.
The remake has Ariel kill Ursula and the king just let's her become human so she stops moping about it.
Also Ariel has amnesia throughout most of the movie which undercut the drama of the situation. If the main character doesn't care about something it's hard for the audience to do so.
