Some elaboration. At the climax of the movie, Nada is powerless. The aliens outnumber the human race but the sheer advancement of technology, most of the humans are already hypnotized, and most of the resistance (that we see) have been shot down, even if he did destroy the satellite, the aliens would probably just rebuild it again, that is, after they kill him, so in the end-as Holly tells Nada-shooting the satellite essentially won't do jack shit. So what does Nada do? As multiple helicopters circle him, he pulls another gun out, shoots Holly, and finally aims the gun at the satellite with his last words: "Fuck it."
The transition shot of Nada and Co walking out of the warehouse between the police driving into pursuit. The extreme close-up of Nada is one of the best transition shots.
