4,6,3,5,2,1 in that order for me, with Star Wars being head and shoulders above the rest, just for what it meant to a 8 yr old boy counting down the days until his dad took him to the Worthing Odean to watch it!
If you had told me ten years ago that there would be three worse Star Wars films than that Ewok-fuelled garbage, I'd have laughed. How wrong I would have been, and how sad I am that it's true.
Episodes 1 to 3 are essentially 'Jar-Jar Binks's screentime in reverse order'. Episode 4 will always have that special wow factor of having queued around the corner to get in for the 5th or 6th time, but ultimately Lucas is a shit director and episode 5 is better for not being his.
I always laugh when people say this...He's produced two of the biggest franchises in movie history and just because he's not done a film about how badly a race was treated in the second world war or done a 19th century costume drama or made a biography of a stupid man from Alabama, people think he's a shit director.
Personally, if having made the Indiana Jones films and Star Wars films constitutes being "shit", then I doubt if Lucas will lose too much sleep over it!
