As one who was raised in the religion and often scared shitl*ss by its violently unforgettable messages of upcoming destruction, I find the video incredibly bland and boring. Too much icky sugar man.
Replace some of the identifying words (e.g., "Jehovah") and you get a video that is virtually interchangeable with any number of current Bible-oriented religions. The Watchtower is giving increasing evidence that it is becoming more and more like the soft and squishy Seventh-Day Adventists.
You think JW kids will love it and rush to remember the words? Of course the little darlings won't. Like kids all over the world, they'll clap their hands for a minute or two and then rush on to do something else with Mom and Dad harping at them to learn the words. Now under that kind of willful circumstance I can imagine JW parents being determined to hold their children's hands - family prayer or not - real tight: " Now learn the friggin' words, honey!"
