Demi Lovato is born with that fat grin on her mouth, right?
She doesn't close her mouth once during the whole movie. It really bothered me! That ugly grin - it felt like, the producers told her: if you stop grinning even for a second, we will beat you up!
It just felt too unnatural and made her seem ugly and a bad actress.
That was all, I had to let this out - because I liked this movie - just couldn't stand the close-ups on her face every second scene with her totally unnatural big grin.
