When Tyler Perry’s new movie buried the new George Clooney flick and the new Cate Blanchett and Mark Wahlberg films as well, a lot of people began to ask why.
USA Today has a succinct answer:

Perry has managed to tap into a tough fan base, one that rarely goes to movies. Married’s faith-based audience, like that of The Passion of the Christ, did not show up in many studio tracking polls.
“It’s a group that doesn’t have a lot of movies made for them,” says Paul Dergarabedian of Media By Numbers. “So if they find a filmmaker they trust — and they trust Tyler Perry — they’re going to turn out.”
