That's a pity about the cancellations in UK. I went tonight and saw it in IMAX 3d. The tickets are almost twice of the regular ones, but the theatre was quite full and in my opinion it is the only way to really enjoy the stunning visuals and cinematography. Its definitely safe for kids as long as they don't go asking questions about what exactly that stuff is in all those crystal cylinders. It was a great piece of fantasy entertainment that salutes a lot of different syfy/fantasy films and fiction genres, everything from Steampunk to Fifth Element, Labyrinth to Star wars as well as a bit of political commentary about people who have way too much money and value profit over human lives. And because two of the big baddies survive the cataclysmic ending, there's a good likelihood that we will see the other two films of the planned trilogy. No worries that it won't make much money in some markets, because when it hits Japan and China its going to be HUGE.
