go ask any kid roughly in their early teens what the movie was about and they will not mention anything of the whole political storyline because they didnt get it...
its fine that adults understand it but Lucas says he wants to make these movies for a new generation of Star Wars fans...
and as for acting... if you truly believe those were the only bad performances than you really need to watch the movie again..
no offense to Nat but she was so scripted it wasnt even funny....
her performance was emotionless and drab...
you cant really mention many actors who had bad performances though considering half the damn people were CG
