I'm afraid to say I went to sleep for the end of this film - I didn't really like it at all (except for Snape bit). I too was frustrated at the way they didn't formulate their horcrux quest at all.

What sort of annoys me about the Harry Potter films/books is that the last two are definitely NOT for young children whereas the first few are aimed at those in primary schools. So, Holly's friend is forbidden to go and watch the films even though she really wants to - and she doesn't understand why :(
