If you consider it cheating to have three movies take up a single list entry than just pretend that heading actually reads The Empire Strikes Back and we can all move forward happily.
I don’t think I really need to explain why these movies are here. If you grew up with them you completely understand it. They’re about as iconic as movies can get, full to the brim with characters, moments and references that are prevalent in our culture today. Watching all six movies on blu ray recently reinforced that these movies are undeniable classics that absolutely need to be on my list. It also reinforced that the new trilogy need never be discussed ever again. Ever.
