The Star Wars prequels, Episode 3 in particular, were okay bordering on good. They certainly weren't what everyone was expecting but then there was no way they were going to live up to expectations or the fan fics people spent 20 years getting in their heads about the rise of the Empire. Its like what Robert Zemeckis said about his own sequels "When you make a film that no one knows about, its your baby. When you make a sequel, everyone has an opinion, and you can't please all of them."
Most of the people who think they are bad are fatty nerds who have this nostalgia golden cow view of the OT as being this perfect sacred movies or just whores who jump on the "Prequels suck" bandwagon because people can't form their own opinions.
I'm sorry to say despite being a massive fan of the original trilogy they weren't perfect either. Some spots were downright boring, the characters weren't written as clever as people think, and Episode 6 was worse then Episode 1 and 2 with its only real redeeming qualities the battle porn, Vader's bullshit, Palpy hamming it up, and Boba Fett going down like the bitch he is.
People who grew up with the Prequels, people who watched them like people in my generation did with the OT, don't have a problem with them and at times think the OT is shit. People who aren't such fat ass nerds who can't handle change and can't just enjoy themselves like yourself enjoy the prequels.
People like myself who have read through the old EU know what really bad Star Wars is can honestly say the Prequels are goddamn masterpieces compared to shit that writer like Karen Traviss, Kevin J Anderson, and Vonda McIntyre shit out with the Star Wars name on it. Go read Legacy of the Force, Crystal Star, any fucking thing with Karen Traviss's name on it, The Jedi Prince Series, Planet of Twilight, Darksaber, or watch the Ewoks cartoon and then come tell me about something being bad.
I know I'm going into dickish territory and I do apologize in advance because normally I like and respect you, but seriously go fuck yourself with that tired ass Prequel bashing. It gets fucking old after awhile.
