Star Wars: The Force Awakens

Possible (probable) SPOILERS ahead!

I've seen Star Wars: The Force Awakens (TFA) twice in theaters now.  I may watch it again, or just wait until I can get it on DVD to continue to watch it.  I loaned my set of the first 6 to a student, and she hasn't given them back, so I might have to buy them all over again!

Anyway, it's safe to say that I love TFA, even though I do see some places where there's a little too much missing information, or improbable coincidences.

There are several reasons why I love it.  It's action-packed and funny.
But more importantly, it's a Star Wars film.  The universe is the Star Wars galaxy, unlike the prequels.  Those were so CGI'd and glossy that none of it felt like Star Wars.  This one does.  The gadgets are similar, the machines are worn, it's just Star Wars.
It's also a pretty similar story to the original (A New Hope); there's a hero(ine) who lost their parents who is stuck on a desert planet and is untrained and mostly unknowledgeable about The Force, who goes on an adventure with the resistance to save the galaxy.  There's a villain who's taking orders from a more evil villain.  There's an unnecessary cantina scene.  There's a feisty woman who saves herself.  There's a crazy scary monster scene.

But I do have some problems, or questions.  Here they are:

1. Why does Finn's conditioning not work?  Does this happen often?  Is he special in some way?
2. How convenient was it for Han to find the Millenium Falcon at just that moment?  
3. Why didn't R2-D2 wake up when BB-8 first came to him with part of the map?  Why did it only happen after the Starkiller was destroyed? 
4. Is Rey just a random girl who is strong with The Force?  Is she an Organa-Solo?  Is she Luke's daughter?!  
5. Why can Rey speak every language?!
6. Did someone take care of Rey when she was first abandoned?  Who?  Was it that old guy with the map (Lor San Tekka is his name; I looked it up)?
7. How convenient was it that Han took Rey to the place where Luke's lightsaber was?

After watching the movie, I have read some things about it.  People have interesting theories about Rey!  I hope that Disney figures out that people (adults, boys, girls) want Rey merchandise!

I can't wait for Episode VIII!!!
