From living undergound, Simon and his 'bro' Kamina escape their world by drilling. Joining other humans in their fight against beastmen, the ultime battle is between Spiral (evolution) and Anti-Spiral, using their Spiral-power to create larger and lager mecha's.
"Who the hell do you think we are?!!!"
According to Anti-Spiral, the Spiral way of life will ultimately end the Universe: literally spiralling out of contol.
"To defeat rationality, to do the impossible to make the possible come true, that is the Team Gurren way!"
The idea, bigger and bigger fights, first "practical", then more and more abstract (Spiral vs Anti-Spiral) isn't new, but again, here it works. Somehow you aren't put off by the ever-increasing power of their minds and mecha's.
Is it because basically the fight is between mentalities (only taken to the extreme?) Hard to say, but a great watch.
Though those Japanese and their bouncy D-cup cleavages... one keeps wondering.
