Syfy has canceled its Superman prequel series "Krypton," according to the Hollywood Reporter.
"Krypton" will not move forward with a third season. THR cites flagging viewership numbers as the cancellation's cause, with "Krypton" season 2 drawing an average of only 408,000 live viewers per episode compared to season one's average of 1.8 million.
"Krypton" season one marked Syfy's most watched debut series in four years, with the premiere drawing its best series premiere ratings in three years.
Syfy's planned "Krypton" spin-off show Lobo has also been canceled.
