15 of the best movie prequels ever
Star Wars Episode III: Revenge of the Sith (2005)
The best (or least worst) of George Lucas' Star Wars prequels finally gave long-suffering fans what they wanted to see from the prequels – Anakin Skywalker's descent to the Dark Side of the Force and his rebirth as Darth Vader.
Ian McDiarmid once again steals the show as a Mephistophelian Emperor, corrupting young Anakin – though in the event Darth's turn to the Dark Side is a bit abrupt.
Despite some truly dismal dialogue, true Star Wars fans can't help but get a kick out of the climactic lightsaber fight between Ewan McGregor's Obi-Wan and Hayden Christensen's Vader.
