If you're expecting a work-of-art superb European classic cult film, look elsewhere, dimwit! This is a wonderful comedic romp. I loved it, my kids loved it, and wife wife & father loved it too. A non-stop giggle-fest.
For me, as for other Christina Ricci fans, this is a movie that you must see but I am pretty sure that you will find it to be very childish. It is a detective and child adventure where you can expect some kind of fun. As said before, Ricci fans must have this movie as a part of their collection, but I will buy other movies from her first.
