The way i see it came to be because of my friends response when i asked him why he liked Gurren Lagann, the show is nothing but yelling and constant action scenes however none of it make sense at all (Whoever yells lowest because strongest what ?) However my friend decided to use symbolism as a reason for liking the series and from what i can tell his symbolism fit the story and how it progressed so i accepted his reasoning opposed to others who claim its "A MANLY ANIME" or something of that sort
Anyway, with the 00 Movie i sort of put everything under representation that later led to the final message at the end of the movie "Peace cannot be kept by force. Only by understanding". The ELS represent war itself, it spreads and involves innocent people (the school girl, Louise, other civilians) and how they absorb attacks, grow in numbers, become stronger as the war keeps going. They attract themselves to the people of Earth (In the movie it was through electronics, attacking other with high quantum brainwaves). Descartes Shaman the innovator revealed during the movie represents the world when the respond to war with more war, even if they have the upper hand in the beginning they become sucked into the war and later consumed by it.
Setsuna represents peace, though his attempt to understand them failed the first time because he did not want to understand their pain however he did not give up and continued to make reason with them through his new Gundam, 00 Quan[T]. After feeling their pain and accepting it he finally understood and was able to make peace with them resulting the the flower at the end and the final message after the credits.
It may sound like a load of B.S but thats how i saw the movie through my eyes
