What do you think of Demi Lovato singing "Let it go"?

[BUBBLEGUMBEN10]

Personally, I think Idina Menzel (the voice actress/singing voice of Elsa)from the Frozen movie should've done a music video with the extended lyrics instead of Demi.
She kept singing the part "Turn away and slam the door" as "Turn my back and slam the door" instead.
I like the original way of that part of the lyrics.
Plus,the music video was pretty boring.
She didn't do anything to make the music video more magical for Disney fans.
I get the whole idea of having Disney star's singing covers from Disney movie's,  but even Jump5 did better doing the "Beauty and the Beast" song.
At least they danced on it.
All Demi did was sit around and then take furniture protectors off of furniture that looks like it came out of the Frozen movie.
What do you think of it?
