I went with my husband, 9 year old daughter, her friend and my 13 year old son. We all enjoyed it although my son didn't want to admit it :-). The only thing is that the 3D wasn't necessary to enjoy the movie. Save yourself some money and see the regular one instead.
I wasn't so sure that I would get the fun out of the movie that my daughter was going to but I was pleasantly surprised. It's a good movie that I would see again.
