Harold and the Purple Crayon (out Sep 12) is based on the 1955 children's picture book and is about the tale of a 4-year-old boy who, powered by a magic purple crayon, can draw anything he wants and then make it come to life. The writers have gone with a live-action adaptation (like the idea) but I expected more laughs and creativity. The characters’ misadventures aren’t particularly interesting. Grade: C+.
