The whole movie makes no sense.
Why even bring an unknown element (Data) on a top secret mission like this? Why did you need people on the ground doing scans when sensors have been shown to give incredible accuracy from orbit? Why hide a spaceship with transporters and a cloak in a lake?
Dougherty deserved to die for his sheer incompetence and Picard should've been drummed out of the service for continuously disobeying orders.
One of the dumbest fucking movies I've ever seen. They had an interesting concept but fucked it up just about every way imaginable.
