We watched it Sunday night.
What a poor ending to the series. Characters we have known and loved for years were given tiny, bitty scenes, if at all. The scenery was so dark we had to guess what was happening some of the time. Endless scenes of students running hither and yon, then disappearing all together.
They did a good job of explaining the complicated bit about the wands for those who haven't read the books (or at least I think they did). The story of Snape was pretty good, could have been better. No movie can seldom match a book but others in the series came closer than this last movie.
