After a short season 2 of Heroes season 3 is a far more epic affair. The 25 episodes comprise of two volumes "Villians" and "Fugitives". Of the two, volume three "Villians" is the better storyline with the various heroes having to create allegiances and taking sides over a possible future which could destroy the earth, and as more information comes to light it causes some to switch sides. Volume four is "Fugitives" which charts Nathan Petrelli's rise to political power which ultimately corrupts his judgement and causes the various heroes to literally run for their lives and reveals the true origins of "The Primatech Company". The storyline also follows Sylar's search for his own origins and sense of purpose. All in all this is a far better effort than season two, though perhaps a little too long.
