This classic story is given the Hollywood treatment - meaning it hardly resembles the book and ends up all sugary and Disneyfied. Even the dialogue seems to have been especially written for the Yanks in places.
I loathe Eddie Izzard - but he does an admirable job of providing the voice of the Psammead (which is a little too CGI for my taste).
In short, this will keep the kids quiet for an hour and a half, but the original book is preferable.
