I've just googled the movie to find out what it was about. It was released in 1987 and said that it made 30.8million at the box office (considered a flop), predominantly in the US and Canada. ...
From Wikipedia:
Box office
The film was initially a modest success,[7] grossing $30.8 million at the United States and Canada box office,[8] on a $16 million production budget.[9]
That word, flop. I do not think it means what you think it means.
