Quite possibly one of the best stories ever told. The basic story of Anakin Skywalker's fall to the Dark Side of the Force and his redemption. It used to be that no one except for true fans liked the series but now with the release of Revenge of the Sith, everyone loves it and the true fans are not unique anymore.
PS. It is also said to have been ruined by Jar Jar Binks, but anyone who says that fails at life.
Man 1: Hey, did you see Star Wars Episode I one TV last night?
Man 2: No f***ing way! The Phantom Menace has that annoying Jar Jar and he makes me miss all the amazing scenes of TPM because I'm tough!
