So I watched it finally.
Overrated, as Frozen was.
Frozen I gave 7/10, with this it wasn't so good - only 6 points out of 10.
Childish*, very predictable twists, with good visuals (scenography, designs, etc), but problems with pacing, and badly written villain motivation made this movie far less entertaining that it should be.
*I know it's animation for children. But Pixar and old Disney always can make movies for children, that was highly entertaining for adults too.
