I'm not choosing... I just have a preference!
I know ep 1, 2 and 3 were not as well recieved for Star Wars but i thought the third in particular was ace! It has been awhile since i have last watched it but i felt it bridged the gap between the first three and last three well how he became Vader etc!
I had only watched the Indi films for the first time a few years ago and i thought they were great films! Don't know how i managed to miss out on them for years!
