Since it's Easter, we watched a family movie today and went with Wonka. I thought it was fantastic. I'm a big fan of the Gene Wilder version from the 70's, but this was on a different level entirely. It's an origin story, adding in a new backstory for Wonka's character and captures the Roald Dahl feel perfectly. If you want a feel-good movie that's fun for everyone, I highly recommend it.
Roald Dahl also wrote Matilda, Witches, BFG, James and the Giant Peach.
