No. There are tons of immoral films making big money in America. It's just that this movie sucks so bad that even liberals won't go to see it.
The movie "sucked". We don't want this decadent crap for movies. Pitt is a sex object and this movie was porno for perverts and desperate wives.
Word spreads fast, and if a movie just sucks, people will tell their friends to warn them not to go.
