The best-selling first novel by Audrey Niffenegger, The Time Traveler's Wife, is now a movie. The screenplay was written by the writer of Ghost, which the reviewer uses to prove that romance and SF can be compatible. (I'd quibble that Ghost, an excellent movie, was clearly a fantasy rather than a SF story.) The reviewer also argues that TTTW is not SF since the time travel mechanism is given short shrift. I think this is true, but was a strength of the novel. The new author wisely did not get wrapped around the axle with physics; the story was self-sustaining without it. Nevertheless, the reviewer finds the screen adaptation worthy, but not perfect. Here is the review of The Time Traveler's Wife via Sci Fi Wire.
