My just turned 8 y/o has seen all of the first 3 and the first of the second set. We haven't seen the new one. Last year we all dressed up as Star Wars characters The kids enjoyed that but don't ask to watch the movies again. We had a lot of good discussion about good v. evil, controlling your anger and dealing with feelings. We are very careful about what the kids watch, dd is more sensitive than ds but he wouldn't like anything too violent either.
