Didn't really care for this version, as a Willy Wonka fan, I didn't think it was much of a prequel. It seems like more of a story of something that happened to Willie before he became with a chocolate maker. They changed the race of Slugworth which sucks, they changed the whole town and he lived in and many other things that were traditional with Wonka.
I would recommend seeing on Amazon in the future than spending the money at the movie theater.
