Cmv: star wars episodes i iii are better than iv vi:
Just completed a marathon of the series, and for my money, the first three were just more enjoyable.  

The story was quite rich; the rise of Palpatine, the clones, Amidala, Anakin, the role of the Jedi... Each arc wasn't just a progression of linear events building up to Episode IV.  

There were some amazing set pieces too; Darth Maul against Obi Wan and Qui Gon, Anakin vs Obi Wan, Jango Fett.

Next to the new ones, the old episodes seem slow, linear a little dumb.

I accept there are plenty of faults with the first three episodes (I'm looking at you, Jar Jar).  I also accept that much of what we accept now as standard fare for sci-fi is off the back of Star Wars, but my argument is simply that the first three episodes (in episodic order) more enjoyable and engaging than the latter three.
