I *strongly* believe you can use movies and TV series to improve social skills! You can use these shows to mimic behaviors and also to build a script of lines you can apply to social situations similar to the ones that come up in the movie/tv series you watch. Heck, I'll even give you a list:
Psych (this is a laid back comedy but the two lead actors are extremely good with using facial expressions, tone of voice, etc. They also make fun of social expectations by mocking them, but in doing so they actually can teach you about the correct ways you can handle certain social situations).
Big (ok, I know, second comedy, but Tom Hanks has an ability to exaggerate facial expressions and mannerisms that make it easy to ready his emotions. While most neurotypicals won't make it this "easy", you'll get a lot of fundamentals of social cues from this movie).
L.A. Confidential (there's a lot of social nuance in this movie that you might have to watch a few times to figure out. But it'll help. There's also some great lines to "cop" for your own. Also, one of the main characters, Sgt. Edward Exley isn't SUPPOSED to be an autistic character, but he's the BEST autistic character I've ever seen. He's nerdy, takes rules literally, has a high sense of justice, but he can also be a bad ass. God, I wish they'd make autistic characters with more depth like that).
Law and Order: SVU (the actors are exceptionally good at conveying emotion. And since the series is about handling sexual issues, there's a ton of emotion throughout each episode. It's a huge opportunity to read expressions based on the type of emotion that person has).
Breaking Bad (this series is awesome because the characters are trying to deceive each other, so you get to see what lies and deceit look like. The best season was season 3. I won't ruin it for you, but there's some really slick characters in there.)
The Truman Show (this movie is perfect because it's about actors trying to act like their not acting. You'll have to watch the movie to understand. It gives you a good look at emotions and is well acted).
That should get you started. Seriously, I watch movies multiple times when I enjoy them, and I'll adapt lines from them all of the time. It also helped me pick up on social cues and understand emotions under certain circumstances. You just have to be able to tell what is portrayed as real vs. what is bull crap. Because, Hollywood is full of bull crap.
