There are a few references of religions that are almost permanent in all Hollywood Series; you have some hints, episodes that just have to be there:
1)The Christmas episode, a problem is there but gets resolved by some kind of Miracle and while at it some skeptic or someone who lost faith gets it back.
2)The Jewish hints, some wedding, a Jew who doesn’t celebrate Christmas, some random guy that passes temporarly.
3)The Muslim with some dilemma caused by the difference in culture.
4)The Buddhist with the unusual problem.
5)The Atheist that is causing trouble all around him.
6)The Satanist with the tattoos and piercings (as if being Goth means satanist).
7)Some minor cult or religion that people barely know about.
All that translate to: Its good to be Christian, its even better to be newborn Christian. To be a Jew is okay, as long as you don’t appear too jewish.To be muslim is a problem. To be Buddhist is exotic and fascinating but its not really practical. To be Atheist is just evil, go away! To be Satanist is a bit less evil than being atheist, because god is merciful. And last, if you have a weird ass religion, then you are one messed up bastard, go away we don’t need you.
I bet if you watch any series and I do mean any series, you will notice these immediately if you look for them. Enjoy :P.
Yeah I know…weak post. I did not know how to write it properly.
