How to Kill the Bad Aliens Now? (Score 2, Interesting)

In Hollywood movies such as "I, Robot" and "Independence Day" a non-swarm organisational structure is assumed and actions by the hero, such as destroying the central processing core or blowing up the mothership, generally puts an immediate and dramatic end to the world's invasive trouble. What would happen in a movie where the invasive enemy had a swarm organisation? I'm not a movie buff at all, so can anyone point out any examples of this? Perhaps Hitchcock's "The Birds" (which I haven't seen) or some killer bee-type movie? On the other hand, movies like "I, Robot" and "Independence Day" also glorify the worth of individual thinking to benefit the whole, but more in terms of exceptional individuals who stand out over the rest, rather than to point out how a group of independent-minded individuals can overcome obstacles. (Again, any examples to the contrary?) Yet, it seems to me that it would be more beneficial to society as a whole to propaganise the swarm organisation. Will Hollywood catch on--with effect--or is Western society too enamoured with the cult of the individual for it to make a difference?
