Conan writer on "flopping at the box office"

The Conan remake had 4 writers on board, one being Sean Hood who replies to the question "what's it like to be a screenwriter for a flop?"
He mentions that a crew of people laboured for years not exactly hoping for the results, which people often forget the work involved. A flop doesn't necessarily make a bad film does it?
