I watched something on TV about it around 4 years ago. I think it is appropriate for an older child, but might be a little scary for a younger child. They do show Jesus dying on the cross. Some of the kids watching were a little scared. The guy who played Jesus did a great job. It looked pretty real, on TV anyway.
I think looking for video on youtube might be a good way to go, or has anyone at your church been? I never new that the Holy Land experience existed till I saw it on TV.
