I knew that inevitably they would have to cut some things out of the movie but the items that they added really didn't need to be added. I was excited to see Snape throughout the movie but I think he could definitely have been in more scenes! I was definitely disappointed with how they changed the climax of the movie as well and the fact that they didn't give you any background information on the horcruxes. Overall I thought the movie was alright but I don't encourage re-reading the book before you see the movie, otherwise you will be very disappointed.
