What is the Proper Star Wars Viewing Order?

Watch the films in the order George Lucas intended. Starting with Episode I and going on straight through to Episode VI.

Pros: This is the way the story naturally flows, and as George Lucas intended it to be. Also, this leaves off where episode VII picks up.

Cons: If you happen to be watching these with someone who hasn't seen any star wars yet, (believe it or not these people do exist) you'll ruin what is one of the biggest theatrical surprises. Also the first three episodes are kind of just back story for the original trilogy.

Watch the films in the order they were released, starting with Episode IV-VI and then I-III.

 Pros: You get to experience it again most likely the same way you experienced it your first time watching the saga. If you're watching it with someone who hasn't seen them yet they still get to experience the big surprise.

Cons: There aren't many, really, other than the fact that it's "out of order." One could argue, however, that viewing (depending on what version of episode VI you are watching) in this order doesn't work because now you have no idea who Hayden Christensen is as a character since they edited him in instead of Sebastian Shaw at the very end of Episode VI. Also, you'll end on episode III which may result in the jump to VII being a bit disorienting.

Another viewing order that has been proposed is Machete order. The order is Episode IV, V, II, III, VI. 

Pros: You maintain the integrity of the original trilogy and allow for the big reveal to those who haven't seen the saga. Plus, episodes II and III serve as more of a flashback than an entirely separate trilogy. 

Cons: In the true machete viewing order, episode I is removed. This is because you can pretty much get through the saga without it. This can, however, be added back in if you so choose.
