I love Star Wars, even though I never watched it as a child. The first time I saw the Original Trilogy was at the Cinema with my Dad when Mr. Lucas decided to re-release the episodes with extra special effects, etc. I wasn't too impressed with Episode IV, but I absolutely loved Episodes V and VI, with VI being my overall favourite.
I'm also a fan of the New Trilogy, with Episode I being my least favourite, II being the runner up, and the almighty Episode III beating the others into a bloody pulp. So much emotion, so much drama, so many loose ends tied up all in the space of three hours. Excellent stuff.
Star Wars movies are the only films (besides Lord of the Rings) that I can watch repeatedly without becoming bored.
Edit: The Obi Wan/Quigon/Maul lightsaber fight from Episode I is my overall favourite, just so you know.
