Here's a great Star Wars retrospective created by YouTuber Sync0py, it even manages to help make the prequel trilogy relevant. But, it puts a main focus on the original trilogy. The video is so well made, it makes me want to watch these movies again! Here's a note from the editor...
Star Wars: Original Trilogy is the most popular saga of all time and it have a charm which will be never lost. With A New Hope, The Empire Strikes Back and Return of the Jedi, George Lucas made a world at war on the backdrop of a family history.
The prequel trilogy is more my generation, it's not as powerful as the original trilogy but i like Attack of the Clones and Revenge of the Sith. But the better thing of this saga is John Williams, his partitions gives us chills forerver.
