I've never seen a single Star Wars movie, but here's what I know: Episode 4, 5, and 6 are the originals and considered the best by most people. Episode 1 2 and 3 are prequels and aren't that good from what I hear. I was going to watch 4 5 and 6... but should I even bother watching episode 1-3?
It depends on how much time and patience you have as well as how much suspense you want. If you have lots of time and patience and want to build suspense, watch all of them in order (1,2,3...) . If you don't have time or patience or if you don't care about suspense, then watch 4 through 6.
There are also some minor "spoilers" about Death Vader in the prequels, if you didn't already know them, as far as I'm concerned the prequels are fine, they just get too much bad rap from some fans, so it' better to watch all the star wars movies, and it's your call if to start from episode 1 or from episode 4, from the chronological order or from the order that they was originally come out. :)
Watch the originals first, then if you want to then watch the prequels, but you can easily skip them without missing out on that much. But for sure watch the originals first because that's the best way to enjoy them.
Whohoo! Watch all them and become a fangril! Come to the Dark Side! I like 1-3 more than the originals. You should start with the original trilogy and continue with the prequels! Be quick about it! Episode 7 is only 5 days away!
All of them, and also watch Star Wars the Clone Wars, and Star Wars Rebels, and Star Wars:Clone Wars, and Play the Old Republic Games, and Read the books, and say screw you to disney, and stick with Star Wars legends
