My Little Pony: The Movie Reviews
The movie is clearly aimed at kindergartners (who may be frightened by some of the violent images); accompanying adults, expect to be left squirming in your seats.
This one's primarily aimed at kids though, so adults can skip it unless, of course, you're accompanying your little ones. Giddy up!
The story-telling isn't smart enough to hold anyone's attention and the animation specs are so over-indulgent that you just don't feel enamoured by it. The voicing also sounds put-on and fake. It's all a harmless bit of fluff ... but there's just no fun in it!
Ultimately this is an adequate distraction if your children absolutely need to be shown something on the big screen this week.
