The movie kept the interest of my three grandchildren. However, I wonder how much more it cost per ticket for the 4-D effect. Nothing more than an index card with 8 scratch offs that all smelled the same. Imagine a dark movie theatre and a number blinking on the screen that tells you which number to scratch off and smell. You have about five seconds to scratch and smell as the movie moves on. Kids have a hard time finding the number in the dark let alone scratch and smell. They were upset they all seemed to smell the same. Would have enjoyed the movie without the 4-d effect more.
