Ep 4-6 are beautiful "classic" space adventure movies which rely on simple and clear things: You get a protagonist, he is in trouble, he got friends, the enemy is overwhelming, he gets at his lowest and succeeds by believing in himself and his friends. There is also some kind of magic power and an old master is teaching our protagonist how to use it.Old fashioned and straight forward, never claiming to be deep or intellectual or whatever nowadays wannabe Hollywood fools like Nolan claim to be.
Concerning the prequels, I actually really liked Revenge of the Sith, wheras the other two felt rather average to me.
