I love the original trilogy. I remember back in 1997 when I got the VHS cassettes for my birthday, I watched the movies with my cousin. The first movie began as Episode IV, so I kept asking him what were the first three movies, but he kept telling me it was the first movie. You can imagine how that got a bit confusing. Anyway, from the original trilogy, Return of the Jedi remains my favorite. It resolves the war between Rebel Alliance and the Galactic Empire, Emperor Palpatine is finally defeated, and Darth Vader comes to his senses just in time to save his son and kill the emperor. I love how the emperor is killing Luke with the force, and Luke keeps crying out, "Father!" I really liked the father-son dynamic in this film.
I'm in the minority in having enjoyed the prequel trilogy, all three films. I don't get the extreme criticism for The Phantom Menace. Yes, Jar Jar is annoying, but it's otherwise a good movie. Did anyone really expect the prequels to achieve the quality of the original films? I don't care whether a sequel or prequel is better than the last film. For me, it just boils down to this: was I entertained for two hours? If yes, then it was a good movie.
Do you follow the saga beyond the original and prequel trilogies? For me, they're just fantasy in space, good movies, but... I'm not really a fan or anything. I don't care about the expanded universe. If they made another movie or even a TV series (live-action), I'd be game.
Oh, and what's up with the original trilogy and DVD releases? Why does George Lucas keep screwing around with the movies? I don't care about all of this Special Edition nonsense. I just want to see the ORIGINAL TRILOGY on DVD.
