Heaven Help Us movie review & film summary (1985)
If you remember those little clickers that the nuns used to use, you'll know why I liked the beginning of "Heaven Help Us" so much - and why I had such mixed feelings about the rest of it. The clickers were dime store crickets that made a nice, loud click, perfect for signaling a First Communion class so all the kids would stand up at the same time, and kneel at the same time, and start filing down the aisle together. In an opening scene of the movie, a kid has his own clicker, and uses it to sabotage the nun's signals, so that the whole class is bobbing like a yo-yo.
