I saw it last night with my 8-year old. We left the movie, at his request, just after LV returned, but then we came back in and saw the last few minutes. It was fun to watch but I was disappointed in how some of the plot went awry. I always expect some changes, but the fact that Barty Jr. remained alive seems to indicate--to me, at least--that the next two movies are going to diverge even further from the books.
Barty Jr. is gone. I don't worry about stuff like that. The movies are a clue to what's improtant to Rowling, and most details are not important. Killing off a major character would have added another five minutes to the film without improving it.
