The plot point problem I refer to in MIB3 allow for one of the coolest climactic scenes I have ever seen in a movie. Not as cool as Slim Pickins riding the bomb say, but cooler than the climax of either of the two previous MIB movies. So perhaps we can forget the way more obvious solution to the problem that the MIB agents are faced with, to watch the more dangerous and cool one that is the climax of the movie.
