My personal take as a writer is that if the movie fails to connect it's because audiences will find it difficult to get into a story set on Mars when we all know Mars is an empty and lifeless planet. Wheres in Avatar "Pandora" was only limited by Cameron's imagination and the audience had no preconceived ideas about the alien world he created.
I understand that a story should stand on it's own but the actual marketing of a movie to the public is a major factor for success too.
