It’s a truism in science fiction that the human element provides the conflict and the drama. The bingeing tip isn’t necessarily a compliment: “Invasion” proceeds so incrementally across such a wide range of characters and their responses to extraterrestrial terrorism that you might well lose your way from week to week. The best advice regarding the 10-episode “Invasion” would probably be to sit back and binge, except that once the three-part premiere is over, you have to wait until the following Friday for a new Apple TV+ installment.
