Was looking at the Last Supper Video and at first, wasn't too sure, but after watching the whole episode, I realized how STRONG it was on Life Application. Also liked that Jesus talked to the kids and included contemporary music to reflect on at the end.
That said, some of the videos in this large series wouldn't be my first or second choice. Occasionally the scripts and animations get a little dark or literal for kids. As with all good series, you still need to preview the material to make sure it fits with your kids and with your church.
