After the release of one of the most anticipated films in the past decade, many are speculating and theorizing on the goings on of Star Wars Episode VII: The Force Awakens, but I may be able to provide some much needed insight and clarification from a fan of the franchise from a long time ago in a galaxy far, far away.
Many seem to not be quite sure whether or not Rey is truly a Skywalker or not, but this perplexes me a bit as it is straight up stated by Rey in the film. After the scene in which Luke, formerly Anakin's lost lightsaber calls to Rey, Maz Kanata says something to the effect of "I can see it in your eyes, those you wait for on Jakku are never coming back. But there is still one who can..." To which Rey immediately shouts "Luke!" In response.
Pretty clear acceptance of the old blood line. As to how and why she was left on Jakku this is my observation. During her vision after she picks up her family's saber, she seems to be calling to her parents being flown away on a Storm Trooper transport shuttle, just like the one Fin rides in on in the first scene. This likely indicates Rey's mother, whether she be Mara Jade, Luke's love interest from the expanded universe stories, or another of Luke's lovers was likely targeted by the First Order as a high ranking member of the Resistance and a wife to the Jedi who assisted in destroying both of the Death Stars as well as the former Emperor.
So, Rey was likely hidden with whoever raised her, similar to Luke and Leia, by her mother on Jakku before she was abducted, interrogated and likely killed by the Order. This would add even more reason for Luke's emotional distress and shameful retreat from the world which set the events of the entire film into motion. The big tipping point would clearly be his failure to save his sister and best friend's seduction to the dark side of the force by Supreme Leader Snoak.
How Did They Find Luke/Anakin's Blue Saber?
If you'll remember from the Empire Strikes back, when Luke drops his saber after his dear old dad lops his hand off for a chat, it falls down the same pitt Luke did that lands him on the antennae to be saved by Han, Leia and the gang. What you may not realize was that Luke actually fell down what appeared to be a garbage chute that filtered out debris to large by simply ejecting it out of Cloud City.
While Luke may not have been able to fit down the garbage chute, his saber certainly could have and would likely have landed in a room just like the one 3PO ended up in after he got blasted to bits. After which point Maz could have easily bought the saber from some sort of scrap or artifact dealer, or perhaps she even worked at or visited Cloud City herself and found it.
How Did Rey Beat Ren?
If it wasn't obvious enough, Kylo Ren was not exactly in ship shape by his final fight of the film. After taking a direct shot from Chewie's ridiculously powerful bowcaster to the gut, being slashed by Fin and then repeatedly slashed and stabbed by Rey, who is extremely powerful in the force as was displayed several times in the movie. Not to mention Kylo Ren probably hadn't fought another Jedi since he slaughtered Luke's Padawans with the help of all of the Knights of Ren, as was shown in Rey's vision.
Was That Really It With Han?
While this may just be wishful thinking, I certainly hoped for a much more ceremonies send off to the great Harrison Ford/Han Solo in Episode 7. While it was a powerful scene and an excellent character changing pivotal point for Ben/Kylo Solo, I think Han deserved a bit better of a big finale. With some small shred of Star Wars loving hope, he just might be able to, he's certainly not the first character in the series to fall from a ridiculously high place and take a lightsaber slash and live (ask Luke, Obi Wan, Yoda, etc.).
Han could very well have had a number of ways to escape, he could have crawled to a medical droid, got himself patched up and jacked a TIE fighter for a quick escape from the fallen Starkiller base. While I know Harrison wanted Han to kick the bucket in Jedi, I think he could at least have a nice Yoda/Obi Wan/Vader bedside-type goodbye to his family and friends who didn't even mention his death, though they all looked fittingly heart broken. It would just be kind of nice for him to have a bit happier of an ending even if they wanted to just say he died from his wounds after his final goodbyes.
Where Do We Go From Here?
Well, it's safe to say after an estimated $8 billion dollar gross for the film and over $100 million just in pre-order tickets, the possibilities are endless. I felt it was a fantastic choice to carry all of the new characters over into the later films. I think it is safe to say that Kylo will be far more powerful and possibly more conflicted after Snoak completes his training, as with Rey as Luke begins mentoring her. Fin may need to have some cybernetic additions to his spine after Ren's saber slash, R2 and BB8 seem like two peas in a pod, 3PO will find new things to whine about and Po will probably keep kicking the First Order's shiny metal can. From there, the future looks bright for Star Wars fans who have been waiting far too long to get a film this good in our favorite franchise...
