I wouldn't let any media sway you. That goes for pro or anti-religion media. Religious films or secular films both are biased and have to convey a certain point of view to their viewers. Don't get sucked into it and become pawns. Great editing can convince people to believe in "evidence" that is actually not evidence at all. You're better off reading about religion or talking to real people than watching Bill Maher's movie or any movie that supports religion.
