Shazam! aims to say something about staying true to yourself, finding family where you can, and that you don’t need superpowers to be a hero and do extraordinary things, all wrapped in superhero origin story trappings. Those aims are all well and good, but the finished product is so saccharine and hollow, the emotion so manufactured and false, and the goofiness wears so thin so fast, it becomes insufferable and leaves a lingering bad taste.
