God girls what do you think about shows and movies and your walk with God(responses appreciated)

I have been deliberating on something for a while an really need some feedback on it.

Shows like Glee and SMASH have great actors that can sing/act dance, BUT they strongly support homosexual activity. I am a strong believer in loving people and not judging, but I also believe that I am responsible for what I put into my mind/body (food, TV, music)..sort of like junk goes in junk goes out. I know God's word is truth and therefor if anything disagrees with it or rather if it strongly contradicts it ..then I shouldn't watch.
Pretty Little Liars supports homosexual behavior as well, while The Lying Game supports premarital sex (as well as Fox's The New girl & the web series The Rules of Dating From My Future Self ). These shows are funny and hare a great pas time..but what of their audience, what examples are they setting?
What about the twilight series and harry potter..I love those movies! I love analyzing the different camera shots, the wardrobe/costumes, special effects...they're just great quality films that I enjoy...but lets shave that all away...one is about a human female who has sex with her un-dead/vampire to make a half human half vampire child
and harry potter plays with dark magic ( in one of the movies he almost kills draco!).
WHAT AM I TO DO? Do I continue to watch these shows for my amusement and just try to keep in mind what is right from what is not..or do I cut it off. I am a lover of movies/tv I love learning from the actors, I love learning from films and using it in my photography (actually I really miss making short films Fassio..I want to run away and make movies...sigh).....i love art and I'm only begging to explore it (sculpture, film, photography, theater, heck any type of performing or social activity/humanitarianism!!!!)
