"Rock of Ages"
Budget: $75 million
Box office: $56.4 million
Critics say: "Rock of Ages is not a spoof, but it might as well be, given how little there is to root for." —Anthony Lane, New Yorker
What makes it a flop: While the live stage show is still a smash hit on Broadway — much to serious theatergoers' chagrin — the movie adaptation could not recoup its high Budget.
Silver lining: Rock of Ages still did relatively well for a musical, with the sixth-highest opening ever for the genre. It's also very likely destined to become a cult classic.
