For the majority of the movie I was entertained and impressed by the Directors output. I can even forgive the fire scene at Ron's house that was no where in the book. But the ending was bad. It just lost the flow and it felt like the Director was running out of time and "just get it finished" I still recommend the movie and will watch again. So close to fanstastic, but poor execution at the end.
Up starts off carefree and happy, but I nearly cried when his wife dies and they have not realized thier life dreams. Sad when old man is destined for the old folks home. Picks up the pace when the house starts to fly. The talking dog is the best character. Happy ending. Entertaining for the whole family although the very young will struggle with the sad parts in the begining.
Good family fun, but the previews on TV showed all the best jokes. If you haven't seen any previews (and that is unlikely) then prepare for a funny entertainting movie. :)
