"Won't Back Down"
Budget: $19 million
Box office: $5.3 million
Critics say: "So didactic that viewers are likely to feel less uplifted than lectured." —Ann Hornaday, Washington Post
What makes it a flop: Won't Back Down doesn't even succeed as an issues movie — it's been criticized as anti-teacher's union propaganda and a mouthpiece for conservative activist Philip Anschutz.
Silver lining: For all its valiant attempts, the film doesn't appear to have done any serious damage.
But interesting list!
