OK movie: Strong start, long slow middle and decent end. Bottom line - HP7.1 feels really stiff for a movie with so much action. Why? Stiff delivery, occasionally relieved by crying (on cue and sometime for a reason) and grimacing ("look jealous, Rupert" "Jealouser!).
[SPOILER WARNING!] I actually like the actors playing Harry, Ron and Hermione, but when the three take over adult bodies - played by 3 different adult actors - I realized just how wooden they can be. The adult "Harry" moved about in this hilarious stiff-armed way that just NAILED Radcliffe's style in these films. It underscored how unnatural Radcliffe often looks. Because most of the young HP actors move in a similar way, I'm blaming the director's directions.
After the saddest first 10 minutes of almost any movie, Up climbs out of those stark depths mile by earned mile. It then stays aloft, emotionally and 3D-realistically, for most of the next 80 minutes. I won't give anything away (that'd be criminal), but look for the double-takes and the Nick Park tribute. When the movie finally returns to Earth, its a whole new, wide-open world, where sharing ice cream cones says more about love, and more honestly, than a sermon.
