David Eick, co-executive producer of NBC’s SF series Bionic Woman, confirmed to SCI FI Wire that the network has indeed canceled the show, though the network has not yet officially said as much.

Well, you had to expect it. The show was intriguing, but ultimately it fell flat. See Terminator: The Sarah Connors Chronicals for a better example of how to do a SciFi series.
