With only a few more days left until Star Wars: The Force Awakens finally hits theaters, most fans seem to be getting their marathon on. Original films and prequels alike need to be rewatched during this anticipatory time, but that time is running short.

Honestly, we're not sure why anyone would willingly do this. But it is an option. Thank you, internet.)
(Also an option for those short on time is this concise recap of the existing films.)
