10 Changes That Make Beauty And The Beast Worse Than The Original
7. The Enchantress Appears In-Film
This shows some of the contempt that major studios have for modern mass-market audiences who apparently cannot think for themselves. Instead of taking the prologue's word for it that the enchantress cursed the prince, his castle, its inhabitants, we now have to be shown she's an ACTUAL REAL character.
Further still, she shows up at the end to actually reverse the curse. The curse is represented by the rose trapped in the bell jar: we did not need a reminder that there was a malevolent witch-like character pulling strings behind the scenes all along. It detracts from Gaston's deviousness.
The enchantress even has her own minor character development, showing a gradual change of heart by helping Maurice recover after he's abandoned by Gaston. Granted, she's the only ally available to help Maurice (given that the Beast hasn't yet changed at that point in the film and Belle is still held captive), but nevertheless having her as a character did not add anything to the film.
It's enough to see that Belle and the Beast change because of the events of the story; having a subplot and minor character hammer it home was pointless.
