Storywise we’re very much in “Hook” territory, in addition to “Finding Neverland” territory. The grown-up Christopher Robin has become a drudge and a slave to the dollar, the way the grown-up Peter Pan in “Hook” forgets his old life and comrades en route to conventional notions of success. “Christopher Robin” does a better job of justifying that story decision. The McGregor character isn’t simply self-absorbed and emotionally distant; he’s trying to save his colleagues’ jobs while cutting expenses on order from above. Once Forster and his design team get McGregor back to the Hundred Acre Wood, and in the bosom of his dear childhood friends, “Christopher Robin” finds its way. The interplay between humans and stuffed-but-very-lively animals is lovely. The voice work from Jim Cummings (Pooh, sweet and sincere as you please), Brad Garrett (a wittily morose Eeyore), Peter Capaldi (Rabbit), Toby Jones (Owl) and the rest holds to a high standard.
