Moreover, there is quite a lot of middle ground between "the PC has unprecedented control over NPC actions" and "they wasted their spell slot and action." This isn't to say that one of these two extremes isn't sometimes appropriate, but most of the time you should be striving to land in between them - rewarding clever illusions without them becoming a universal I-Win button or punching way above the power level of their spell slot.
