I liked Dune 2, but I think I'm the only person who like the first one better. I really enjoy world building and I just found the first movie more intriguing. But they are both excellent.
I saw the new Ghost Busters last night. My kids both enjoyed it -- although my nine-year-old son turned to me halfway through and said "there's not a lot of action in this one is there" -- but I was let down. The nostalgia factor worked again, but nothing else really seemed to. Too many characters, a really thin plot, and as mentioned not a lot of action.
