I saw the Phantom Menace first, and I remember I adored it. Hey, I was a kid, it was more or less made for me. I loved Jar Jar Binks the Bumbling Sidekick, and I liked all the amusing sounds and flashes. Also, there were kickass robots. I really wanted the robots to win.
Then, I saw the first three films. I liked them as well. Less colour and flash, but enough to keep me interested. Also, I fell flat for Darth Vader. I thought he was so damn cool with his cape and raspy breath.
Then I saw the other two prequels. They fell alot flatter. But by then, I had realized I just came into a Star Wars film for the lasers and explosions anyway, so it didn't matter very much. I had enough sense to find Anakin's preformance cringe-worthy, however. Sort of ruined my relationship with the old chainsmoking sod.
Now that I've grown a modicum of taste, I'd say the original three is better. The prequels are not entirely awful, but I wouldn't want to see them sober. But it's still just Star Wars. Good films and responsible for bringing sci-fi into furnitured rooms, but it's still just Star Wars. There's loads of better films.
And because I think it's related... I saw all the Indiana Jones-films as a kid. I still like the Kingdom of the Crystal Skull. Not the best one, but it's a good Indiana Jones-flick. I never felt like George Lucas had done indecent things to my nostalgia, pretty much because I didn't have any real nostalgic feelings to the first three. They weren't a monolithic part to my childhood or anything, they were just amusing little films about adventure and nazis.
Furthermore, the fridge-scene is my personal highlight of the series. I'm sorry, but I love it. Makes about as much sense as anything else Indie gets involved in.
