I completely understand where most people's dislike of the second Star Wars trilogy springs from. It started with politics and Jar-Jar Binks in Phantom Menace and then hit rock bottom with Hayden Christensen's portrayal of Anakin Skywalker. However, as frustrating as the prequels are, they're not entirely devoid of cool moments. We get to watch Yoda bust out his lightsaber and do some damage, and the showdown between Palpatine and Samuel L. Jackson's Mace Windu is still pretty great.
My favorite moment in the entirety of the new trilogy comes at the end of Revenge of the Sith -- in a scene many a fanboy and fangirl fantasized about from the very moment these films were announced. That's right -- the moment where Anakin finally becomes the Darth Vader we all know from the original (and better) trilogy. It's one of the few things the second set of films gets right -- the showdown that leads to Anakin donning the imposing black suit with the built in respirator and transforming from a whiny child into what is arguably cinema's greatest villain is everything I'd hoped it would be. It almost makes up for all the terrible things that have come before -- yes, even midichlorians -- but not quite. Just in case you haven't seen this film and have no clue how Anakin becomes Vader, consider this your spoiler warning.
