On the subject of Maleficent, it totally counts. It IS a remake of the original Disney Sleeping Beauty movie. Maleficent and the Good Fairies have the same designs, and they even went out of their way to remake Aurora's original reveal scene where Maleficent put a curse on her.
Also, I nearly forgot about this but check out this rocking, brand new song they wrote for Maleficent!
Now, the movie does have its own focus and direction that makes it more than a remake, but that doesn't mean it's not a remake. The plot still follows Aurora growing up, pricking her finger, and falling into her traditional Sleeping trance. There are huge divergences from the original story, but there's too much of the original story still in there to not call it a remake.
Regarding the Alice films, I'm inclined to count the 1st one considering that its success is what led to Disney greenlighting all these live action remakes of their animated properties in the 1st place.
