As the book is at some parts too long, so is the film. No ... wrong, the film is about one a half our too long: due to the fact, that the film presents no excitement. As soon as there is at least a bit of action, it is already over and the viewer can go back to see the tent at different locations ... The 7th book presented so many options to make a great movie out of it, but David Yates failed totally. But I do think it isn't his fault or the fault of the actors (they did a good job, given the bad script) - it is only credited to the fact, that JKR had too much control over everything. I think the second part will be a bit better, but only because of all the action and fighting and I think a lot of people only want to see the glimpse of the future of the main characters.
