That's a wrap on the new Showtime horror series Penny Dreadful: City of Angels, as the network has announced that the series has been canceled after its first and only season. Premiering in April, the show was a spin-off of the acclaimed series Penny Dreadful, which also ran on Showtime between 2014 and 2016. The season one finale, which aired on June 28, will now serve as the series finale as well with no new episodes in the works.

"Showtime has decided not to move forward with another season of Penny Dreadful: City of Angels," the network said in a statement addressing the cancelation. "We would like to thank executive producers John Logan, Michael Aguilar and the entire cast and crew for their outstanding work on this project."

Created by John Logan, the original Penny Dreadful featured many iconic characters from the public domain, giving the story an interesting who's who of horror personalities. Its cast included Reeve Carney as Dorian Gray, Timothy Dalton as Malcolm Murray, Eva Green as Vanessa Ives, Rory Kinnear as the Creature, Billie Piper as Lily Frankenstein, and Harry Treadway as Victor Frankenstein. Although the series consistently pulled in strong reviews from critics, it came to an end after just three seasons, leaving many of its fans feeling like the show had ended far too soon.

When City of Angels was announced, Penny Dreadful fans were hopeful that the spin-off would be able to recapture the magic of the original series. Serving as a sequel series, City of Angels was set 50 years after the events of the original show. Taking place in Los Angeles during the Golden Age of Hollywood, the spin-off starred Natalie Dormer as a supernatural demoness capable of taking various forms. Daniel Zobatto, Kerry Bishe, Adriana Barraza, Jessica Garza, Rory Kinnear, and Nathan Lane also starred. Notable guest stars like Brad Garrett, Lin Shaye, and Brent Spiner were featured in the short-lived spin-off as well.

Showtime did not provide a reason for giving City of Angels the boot, but it could easily be speculated that the show just wasn't as successful as the network was hoping for. While ratings stayed mostly consistent during the show's first and only season, they weren't even able to match the final season of Penny Dreadful, which had declined over the course of its own three seasons. It would seem that Showtime probably wasn't willing to roll the dice on a second season with the first season's ratings seemingly under a glass ceiling.

Like the original Penny Dreadful, reviews also were largely positive with City of Angels. Those who were watching the series did seem to enjoy it, so the news of the show getting just one season is bound to disappoint the Penny Dreadful fan base. The failure of the spin-off also makes it very unlikely we'll be seeing the franchise continue on with any other type of revival or spin-off in the foreseeable future as well, meaning we've probably seen the last of the Penny Dreadful universe on the small screen.
