The first three star wars movies would have been better, if they'd condensed the first 90 minutes into 30 minutes and made the last 30 minutes the bulk of the movie...
The Clone Wars would have been a better name. I guess a lot of the names are kind of cheesy, but I don't know, Attack of the Clones just doesn't have enough oomph to it.
The best names of the series after the iconic 'Empire' are probably A New Hope and The Phantom Menace.
