If he likes the movie, he'll like the show, if not, he most likely won't.
I belive this is a 40 minute show, but unlike Aladdin the length doesn't change as there really isn't any adlibbing in the show (unless something messes up and they can fix it and continue).
In my opinion Aladdin is a much better show, but Snow White is decent (This coming from a guy's perspective). I do think they could have done better at casting Snow White (at least someone attractive would have been good for the lead role of someone whose beauty is supposed to surpass all others), but that's another story.
