If you're going to check out Star Wars, go watch the original trilogy first (A New Hope, Empire Strikes Back, and Return of the Jedi). Episodes 4, 5, and 6 are pretty epic and I like watching them back-to-back if possible. The prequel movies, on the other hand, get some pretty bad hate; while I personally don't find them that offensive, they aren't movies I would watch more than once (just to get Darth Vader's origin story). You should watch them before The Force Awakens comes out if you can.
