I wasn't that keen on the beginning when Harry is in the Cafe. It just seemed so tacky to me. Like Harry Potter would be chatting up some silly cafe worker.
I wanted the Dursleys, I'm sure they could have fitted them in. All they need have done is start by showing Dumbledore in the Dursleys house talking to them. It wouldn't have taken very long.
Or show him waiting outside for Dumbledore, then tey could have maybe had a discussion about the News in the Daily Prophet over the Summer. Anything but that cafe worker!
The rest was ok, missed so much out, obviously they had to. I'm not so sure that they discussed the horcruxes well enough...or dumbledores hand.
